The present invention relates generally to the field of fiber optics, and is particularly advantageous when practiced in connection with single-mode and polarization-preserving fiber-optic waveguides.
Fiber optics is generally concerned with the transmission of light along a transparent fiber structure which has a higher refractive index than its surroundings. Currently it is possible to manufacture long, continuous strands of optical fiber which may propagate signals without substantial attenuation over long distances. It is also possible to manufacture the fiber structure as an optical waveguide wherein only preselected modes of light propagate in the fiber. By limiting wave propagation through the fiber to a single mode, the bandwidth of the optical fiber may be exceedingly high to provide a high information-transfer capacity. Moreover, optical-fiber transmission equipment is compact, lightweight, and potentially inexpensive. Transmission over optical fibers does not generate interference and is unaffected by external interference.
While the development of optical fibers for telecommunications systems is becoming rather highly advanced, the use of fiber optics for sensing and control systems is still in its early development. In sensing and control systems a fiber-optic transducer is used that exploits either multimode or single-mode light propagation in an optical fiber.
While multimode sensors use amplitude variations in the optical signals to sense and transmit the desired information, single-mode sensors use phase variations rather than amplitude variations. The single-mode sensors usually involve mechanisms for altering such properties of the fiber as path length or index of refraction to effect the desired phase variations in the optical signal. In the case of the fiber-optic gyroscope, the single-mode sensor measures acceleration which inherently alters the propagation of light even though the fiber is not affected. Thus, in contrast to multimode sensors, in single-mode sensors the uniformity and mechanism of light propagation and hence the characteristics of the fiber are especially critical.
Single-mode sensors are also sensitive to the state of polarization of the light in the fiber. If the fiber is not significantly polarization-holding or preserving, the state of polarization at the detector will tend to fluctuate randomly. Thus, for single-mode transducers, it is desirable to use elliptical-core or other kinds of polarization-holding fiber. See, e.g., McMahon et al., "Fiber-Optic Transducers," IEEE Spectrum, December 1981, pages 24-27.
There are well-known techniques for making long, continuous, single-mode optical fibers. Keck et al. U.S. Pat. No. 3,711,262 issued Jan. 16, 1973, for example, describes the conventional method of producing an optical waveguide by first forming a film of glass with a preselected index of refraction on the inside wall of a glass tube having a different index of refraction. The glass tube and glass film combination is then drawn to reduce the cross-sectional area and to collapse the film of glass to form a fiber having a solid cross-section. As a result of this process, the core is formed from the glass film, and the cladding is formed from the glass tube.
It is also known that multiple core and cladding layers may be deposited on the inside of a preform which is then collapsed and drawn, so that the preform tube becomes a support jacket around the core and cladding layers. Light propagated through a fiber formed in this manner is confined to the guiding region formed by the core and cladding layers and does not significantly interact with the support jacket. Consequently the optical properties of the support jacket can be considerably inferior to the optical qualities of the core and cladding. Details of this process for forming multiple core and cladding layers is disclosed in MacChesney et al., "A New Technique for the Preparation of Low-Loss and Graded-Index Optical Fibers," Proceedings of the IEEE, 62, at 1280 (1974), and Tasker and Ench, "Low-Loss Optical Waveguides with Pure Fused SiO2 Cores," Proceedings of the IEEE, 62, at 1281 (1974).
It is known that elliptical-core, polarization-preserving optical fibers may be drawn from elliptical-core preforms. The preforms may be manufactured by collapsing a cylindrical preform or tube, with a slight vacuum in the center. Another method of manufacturing an elliptical-core preform is to fabricate the substrate tube to have a wall of non-uniform thickness and then collapse the tube by heating it to the softening point. The surface tension in the shaped wall, which occurs during the collapsing and subsequent drawing steps, causes the resulting fiber core to be elliptical in cross-section. See, e.g., Pleibel et al. U.S. Pat. No. 4,274,554 issued June 23, 1981.
It is a principal object of the present invention to provide a fiber-optic rotation sensor that requires only a single directional coupler, and in which the directional coupler can be formed from the same fiber that forms the sensing coil.
Another object of the present invention is to provide an improved fiber-optic rotation sensor which accurately locates the axes of birefringence within the fiber that forms the sensing coil. In this connection, a related object of the invention is to provide such an improved sensor which has excellent polarization-holding properties.
A further object of the invention is to provide an improved fiber-optic rotation sensor which has a precisely known path length through the sensing coil, thereby permitting more accurate determination of angular velocity and/or acceleration.
Still another object of the invention is to provide an improved fiber-optic rotation sensor which facilitates coupling of the optical fiber to a solid state laser, and which maintains the polarization of the signal launched into the fiber from the laser.
Other objects and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.
In accordance with the present invention, there is provided a fiber-optic rotation sensor comprising a coil of polarization-holding, single-mode optical fiber; a laser source directly coupled to a first end of the fiber forming said coil; a photodetector directly coupled to the second end of the fiber forming said coil; and portions of said fiber (1) between the laser source and the first end of the coil and (2) between the photodetector and the second end of the coil, being joined to form a directional coupler which (a) couples part of the signal from the laser into the second end of the coil and (b) couples part of the signal emerging from the first end of the coil into said photodetector. The coil is preferably made from a polarization-holding, single-mode optical fiber having a core with a non-circular cross-section defining two transverse orthogonal axes, the outer surface of the fiber having a non-circular cross-section with a predetermined geometric relationship to the orthogonal transverse axes, the coil being wound on a substrate with a constant geometric relationship between the noncircular outer surface of said fiber and the surface of the substrate, thereby accurately locating the birefringent axes of said fiber relative to said core and said substrate.
In a preferred embodiment of the invention, a laser source is coupled to one end of the coiled fiber to supply the fiber with an optical signal having a fixed polarization plane, and the non-circular outer surface of the fiber forms a reference surface for precisely aligning one of the transverse orthogonal axes of the fiber core with the fixed polarization plane of the optical signal from said laser source. The laser source is preferably a solid state, single-longitudinal-mode laser.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will be described in detail herein. It should be understood, however, that it is not intended to limit the invention to the particular forms disclosed, but, on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
Turning now to FIG. 1, there is shown a dielectric core 20 for supporting the propagation of electromagnetic fields E, H in the axial direction. This particular core 20 has an elliptical cross-section with a major diameter 2a and a minor diameter 2b. A single-mode optical fiber has such a core 20 with a relatively high dielectric constant/index of refraction which tends to confine and guide electromagnetic energy (i.e., light) along the axis of the core. It is known that if the index of refraction of the core 20 is properly chosen in relation to the index of refraction of the surrounding medium, the core dimensions a, b, and the wavelength of the light, the distribution of the fields E, H will tend to occur in a single, well-defined pattern, or mode. Shown in FIG. 1 is the field pattern for the o HE11 mode.
Single-mode propagation has the advantage of providing well-defined field patterns for coupling the fiber to optical devices. Another advantage is that the attributes of the light propagation, such as phase velocity and group velocity, are relatively constant as the light propagates down the fiber. The group velocity specifies how fast modulation or information travels down the fiber. Thus, for transmitting information over long distances it is important that the group velocity be relatively constant and in particular independent of frequency so that the information will be localized at a specific region rather than becoming "smeared out" as the information travels down the fiber. A constant phase velocity is important in fiber-optic sensor applications where the phase of a signal in a sensor fiber is compared to the phase of a reference signal in a reference fiber.
Single-mode propagation does not, however, guarantee that the polarization of the signal is fixed in any definite or constant angular relationship with respect to the core 20. Polarization is defined as the direction of the electric field vector E. Thus, as shown in FIG. 1, the light is polarized a vertical direction.
In single-mode fiber-optic sensors, the phase of the optical signal at the end of a sensor fiber is made a function of an environmental parameter sought to be measured. Typically this phase-shift is introduced by physically lengthening the fiber, or by changing the index of refraction of the core 20. But if the core 20 is not polarization-preserving, the polarization of the light tends to change randomly as the light propagates down the axis of the core 20. Such a random change in polarization results in a fluctuation of the detected signal since a 180� rotation of the direction of polarization is equivalent, at the end of the fiber, to a 180� phase shift. Thus, for sensor applications, the polarization of the light should be maintained at a fixed angular relationship with respect to the fiber as the light propagates down the core.
To maintain or preserve the polarization of a signal in an optical fiber, the optical properties of the fiber must be anisotropic, or in other words a function of the angle of polarization with respect to the fiber. One method of making the optical fiber anisotropic is to make the core 20 have a cross-section which is elliptical or some other non-circular shape which defines two transverse orthogonal axes permitting the de-coupling of waves polarized along those axes. Signals which are launched into such fibers in alignment with one of the transverse axes tend to remain aligned with that axis as the signals are propagated through the fiber, thereby preserving the polarization of the signal.
In accordance with one important aspect of the present invention, the core of the guiding region in a single-mode optical fiber has a non-circular cross-section which defines two transverse orthogonal axes for holding the polarization of signals aligned with those axes, the guiding region being located sufficiently close to the surface of the fiber, along a selected length of the fiber, to allow coupling to a guided wave, and the outer surface of the fiber has a non-circular cross-section with a predetermined geometric relationship to the guiding region and the orthogonal transverse axes of the core so that the location of the guiding region and the orientation of the transverse axes can be ascertained from the geometry of the outer surface. Thus, in the illustrative embodiment of FIG. 2, an optical fiber 25 has an elliptical core 26 with a relatively high index of refraction surrounded by a cladding 27 with a lower index of refraction. The dimensions and the refractive indices of the core 26 and the cladding 27 are selected to provide a single-mode guiding region. Because of its elliptical shape, this guiding region will also hold the polarization of optical signals propagated therethrough in alignment with either axis of the ellipse. That is, the major and minor axes of the elliptical cross-section represent two transverse orthogonal axes which permit the de-coupling of waves polarized along those axes.
Surrounding the guiding region formed by the core 26 and cladding 27 is a support layer 28 which provides the fiber with increased mechanical strength and ease of manipulation. Since this support layer 28 is not a part of the guiding region, its optical properties are not nearly as critical as those of the core 26 and the cladding 27. To prevent light from being trapped in the cladding 27, the support layer has an index of refraction higher than that of the cladding 27.
As can be seen in FIG. 2, by removing a thin portion of the support layer 28, and also a portion of the cladding 27 if necessary to achieve the desired degree of coupling (e.g., by etching to the dashed contour in FIG. 2), the guiding region formed by the core 26 and cladding 27 can be located sufficiently close to the surface of the fiber to allow coupling to a guided wave. As an alternative, a selected segment of the fiber can be drawn to reduce the fiber diameter within that segment and thereby expand the field of the guiding region to permit the coupling of guided waves to and from the guiding region in that segment of the fiber.
The outer surface of the fiber as defined by the support layer 28 in FIG. 2 has a D-shaped cross-section, with the flat surface 29 of the D extending parallel to the major axis of the elliptical guiding region on the side of the fiber closest to the guiding region. This D-shaped optical fiber is easily interfaced to a polarization-sensitive optical device by using the flat surface 29 of the D as an indexing surface. As shown in FIG. 3, an optical device 30, such as a solid state laser, has a point source of horizontally-polarized light 31 which may be coupled to the optical fiber 25 if the fiber 25 has its core 26 aligned with the source 31 and if its preferred direction of polarization is also horizontal. To facilitate the alignment, an indexing slide 32 may be scribed or photo-etched on a horizontal surface such as the top of a chip 33. The slide 32 may be fabricated using conventional photolithographic and other microelectronic fabrication techniques. Similarly, two fibers may be spliced coaxially using a chip with an indexing slot to align the flats of the D's.
The guiding region of the D-shaped fiber 25 of FIG. 2 is preferably offset or displaced from the geometric center 35 (i.e., centroid of mass or center of gravity of the transverse section) toward the flat 29 of the D along the perpendicular-bisector 36 of the flat. Preferably, the guiding region is located within a few average core diameters of the flat surface 29 so that the outer surface of a portion of the fiber may be etched to expose the guiding region at the surface 29, thereby permitting the transmission or gradual exchange of light between the guiding region and the fiber surface. For example, the guiding region can be located within about three average core diameters of the flat surface 29. For the elliptical core 20, the average core diameter is the sum (a+b) of the major and minor radii.
The fact that the flat surface 29 of the D is within a few average core diameters of the guiding region does not affect the attenuation or loss of the fiber since the flat surface 29 is not within the cladding 27. Although there is some light propagated within the cladding 27, substantially no light reaches the support layer 28 which forms the flat 29 of the D. But if an etchant such as hydrofluoric acid is applied to the outer surface of the fiber along a selected length, the flat surface 29 will be moved inwardly (e.g., to the dashed contour shown in FIG. 2), thereby allowing light between the core 26 and the flat surface 29 via the cladding 27. A fiber with a central core is difficult to etch in this fashion since there may not be any supporting layer remaining after the etching process.
Perhaps the most important application which requires the gradual exchange of light between the core and the surface of an optical fiber is a directional coupler. Directional couplers are the fiber-optic equivalents of optical beam splitters and are indispensable elements for making single-mode fiber-optic transducers. A beam splitter 40 is schematically shown in FIG. 4. The beam splitter 40 is essentially a partially silvered mirror which transmits a portion of the incident light and reflects the rest. A source of incident light A' is usually directed at 45� with respect to the plane of the beam splitter 40 so that the incident beam A' is split into a transmitted beam C' and a reflected beam D'. In addition to the beam-splitting function, the beam splitter 40 is also used to combine two incident beams A', B'. The incident beam B', shown in dashed representation, may also be directed at 45� with respect to the plane of the beam splitter 40 and at right angles to the incident beam A' so that the output beams C' and D' are combinations of the incident beams A' and B'.
There is shown in FIG. 5 an exemplary fiber-optic directional coupler comprised of two D-shaped optical fibers 44, 45, like the fiber 25 of FIG. 2, positioned adjacent each other on a flat substrate 46. The flat surfaces of the fibers 44, 45 contact each other along etched lengths l, and their guiding regions are aligned to permit the gradual exchange of light between the guiding regions along the length l of the fibers. In the particular embodiment illustrated, alignment of the guiding regions of the fibers 44, 45 is facilitated because the D-shaped fibers 44, 45 are curved rather than straight in their unstressed configuration, with the flats of the D's located on the convex surfaces of the curved fibers. The curving or curling of the fibers is achieved by forming the fibers from materials which provide a large difference in the coefficients of thermal expansion of the support layer 28 and the guiding region formed by the core 26 and cladding 27. These two different portions of the fibers then contract at different rates during cooling after the fibers are drawn, producing the desired curvature illustrated in FIG. 5. With this curvature, the flats of the D's are aligned vertically when the curved fibers 44, 45 are laid flat on the substrate 46. Thus the fibers can simply be moved into engagement with each other along the etched lengths l and fastened together by a drop of adhesive 47.
The operation of the directional coupler of FIG. 5 is best understood in terms of an exchange or transfer of the electromagnetic fields E, H propagating down the cores 48, 49 of the respective fibers 44, 45 as shown in FIG. 6. A portion of the electromagnetic field energy in the incident signal A is gradually transferred from one core 48 to the other core 49. In general, the relative amount of energy from signal A that is transferred from one core 48 to the other core 49 is proportional to the amount of coupling per unit length and the length l over which the coupling occurs.
Directional couplers are used in devices such as single-mode interferometer sensors and fiber gyros. A generalized schematic diagram of a single-mode interferometer sensor using optical fibers and directional couplers according to the present invention is shown in FIG. 7. A coherent source of light such as a laser 51 emits light into an incident port of a directional coupler 52. The directional coupler 52 acts as a beam splitter and sends half of the light into a reference fiber 53 and the other half into a sensor fiber 54. The sensor fiber 54 is coupled to the environment so that the phase of the light in the reference fiber is modulated by a desired environment signal 55 by the time the light reaches a second directional coupler 56. This second directional coupler 56 accepts the light transmitted through the reference fiber 53 and the light transmitted through the sensor fiber 54 as incident signals, and acts as a combiner. Combined signals appear at two output ports 57, 58, one of which (57) is terminated (preferably with substantially no reflections) and the other of which (58) is fed to a photodetector 59.
The photodetector 59 is responsive only to the amplitude of the detected signal at the output port 58. The "beat phenomenon" generates a null in the relative response of the photodetector 59 when the phase difference is 180�, or one half of a wavelength of the coherent light. For maximum sensitivity, the null should be very sharp. But to get a sharp null, the sensor fiber signal and the reference fiber signal each must be phase coherent, and they must have equal amplitudes. The signals will be phase coherent if they propagate as single modes in the sensor and reference fibers. The amplitudes will be equal if half of the light 58 reaching the photodetector 59 passes through the reference fiber 53 and the other half passes through the sensor fiber 54. These proportions are set predominantly by the coefficient of coupling of the directional couplers 52 and 56, so it is important that these couplers have coefficients of coupling that are precisely defined and stable.
To some extent, the null can be sharpened by a null signal generator 59a which generates a null signal on a feedback line 59b to modulate the characteristics of the reference fiber 53. Thus the reference phase may be adjusted by the null signal generator 59a so that the difference between the sensor phase and reference phase is approximately 180�. The relative response is then always close to null.
It will be appreciated from the foregoing discussion that the system of FIG. 7 measures ambient conditions by the changes they effect in the sensor fiber 54 as compared to the reference fiber 53. Thus, maximum sensitivity is affected by the uniformity and mechanism of light propagation and the characteristics of the fibers, the directional couplers, and the connections between them. By using the D-shaped fiber of the present invention, there are no connections or joints in the reference fiber or the sensor fiber other than the couplings at the directional couplers; thus, the propagation of light through the system is not affected by the reflections or changes in optical properties that can occur at fiber terminations. The directional couplers 52, 56 are easily fabricated at any point along the length of the D-shaped fiber so that, for example, they may be fabricated on relatively short lengths of fiber extending from a large spool of fiber comprising the sensor fiber 54.
The maximum sensitivity of the fiber-optic sensor shown in FIG. 7 is ultimately set by the relative change in sensor phase of the sensor fiber 54 as a function of the environment signal 55, and the level of light received at the end of the sensor fiber. Since the total phase change is usually directly proportional to the length of the sensor fiber 54, it may be desirable to use an extremely long low-loss sensor fiber.
In accordance with another important aspect of the present invention, the optical fiber is made by forming a preform having a core and a cladding forming a guiding region which is offset from the center of the preform and has a non-circular cross-section defining two transverse orthogonal axes, the outer surface of the preform also having a non-circular cross-section with a predetermined geometric relationship to the guiding region and its transverse axes; and drawing an optical fiber from the preform with the drawing rate and temperature being controlled to produce a fiber with a cross-sectional geometry similar to that of the preform. The guiding region of the drawn fiber is preferably located sufficiently close to one side of the fiber that the removal of a relatively small amount of material from the outer surface of the fiber allows coupling of guided waves to and from the guiding region.
Thus, the preform can have the same cross sectional configuration as the fiber 25 illustrated in FIG. 2. Such a preform can be made by first forming a cylindrical preform with an elliptical core and cladding located in the center thereof (using techniques known in the art), and then grinding one side of the preform to form a D-shaped cross-section with the flat surface of the D extending parallel to the major axis of the elliptical core. An optical fiber is then drawn from the D-shaped preform at a drawing rate and temperature controlled to produce the fiber 25 of FIG. 2, i.e., with a cross-sectional geometry substantially the same as that of the preform.
A drawing machine suitable for precise control of the drawing process is shown in FIG. 8. In order to heat the preform to approximately the softening temperature, the central component of the drawing machine is an induction furnace generally designated 60 comprising an external induction coil 61 and an internal graphite toroid 62. The toroid 92 is approximately an inch long, an inch in diameter, and has a core hole about a quarter inch in diameter The induction coil 61 is energized by a radio-frequency power source 63 so that electrical heating currents are induced in the graphite toroid 62, the resulting temperature being measured by an optical pyrometer 64 and monitored by a control unit 65 adjusting the power source 63. In order to prevent the graphite toroid 62 from burning up, the toroid 62 is disposed within a vertical glass cylinder 66 which is filled with a relatively inert gas such as argon from a supply 67.
The preform 68 is fed from the top of the cylinder 66 and passes through the center of the graphite toroid 62. The toroid 62 is heated white hot causing the preform 62 to soften. The drawing of the fiber 69 from the preform 68 occurs approximately at the center of the toroid 62. The toroid 62 has legs 71 which stand on a support ring 72 attached to the glass cylinder 66.
The critical parameters affecting the drawing process are the rate of feed Vp of the preform 68 toward the drawing point, the temperature at the drawing point, and the rate Vf at which the fiber 69 is drawn from the drawing point. The temperature and rate of drawing Vf set the tension at which the fiber 69 is drawn, and this tension may be further regulated by a series of tensioning rollers 73 which also assure that the fiber 69 is drawn coaxially out of the bottom of the glass cylinder 66. The rate of feed of the preform Vp is established by a vertical linear slide generally designated 74 having a lead screw driven by a drive motor 75. A vertical shaft 76 is actuated by the slide 74 and extends into the glass cylinder 66 through a gas seal 77. At the end of the shaft 76 is a Phillips chuck 78 which grips the top end portion of the preform 68. The rate of drawing Vf, on the other hand, is established by a horizontal take-up drum 79 below the lower end of the glass cylinder 66. The take-up drum 79 is journaled for rotation and driven by a take-up motor 81 through a speed reduction gear assembly 82. To wind the fiber 73 in a helical fashion on the take-up drum 79, the drum as well as the take-up drive itself is mounted on a horizontal linear slide generally designated 83 having a lead screw driven by a drum advance motor 84.
In one particular example, a preform was made by depositing a pure silica cladding and a germania core on the inside surface of a silica tube. The cladding and core were formed by the thermal decomposition of silicon tetrachloride and germanium tetrachloride, which were circulated through the bore of the silica tube at approximately 1800� C. in an induction furnace. Diametrically opposed portions of the outside surface of the silica tube were then ground flat, after which the tube was collapsed and lightly drawn to form a preform having an outer surface with a cylindrical cross-section with a diameter of about 2.8 mm. and a central core and cladding of elliptical cross-section. One side of the elliptical-cored preform was then ground flat, with the plane of the flat surface extending parallel to the major axis of the elliptical core and located within a few thousands of an inch of the cladding. The preform thus had a D-shaped cross-section. Optical fiber was then drawn from this D-shaped preform at a temperature of about 1790� C. while feeding the preform at a rate of about 0.3 mm/sec. and while pulling fiber from the preform at a rate of about 0.5 m/sec. These parameters were chosen to result in a drawing tension as high as practical without breaking the fiber. The resulting fiber had a D-shaped cross-section as illustrated in FIG. 2, with a maximum outside diameter of about 85 microns. The shape of the cross-section is retained as the preform is drawn into a fiber due to the high drawing tension, the relatively small diameter of the preform, and the precise temperature and localized heating of the induction furnace.
As another feature of the present invention, a unitary directional coupler is formed by inserting two of the fibers of FIG. 2 into a tube with the guiding regions of the two fibers aligned with each other and with the fiber surfaces closest to the respective guiding regions facing each other, and then drawing the tube while heating both the tube and the fibers so that the tube and fibers are all fused together. The fibers are preferably drawn along with the tube so as to reduce the diameters of the guiding regions therein, whereby the fields of the fiber cores are extended further into the respective claddings to achieve a selected degree of coupling between the two fibers. If desired, the coefficient of coupling may be monitored during the drawing operation and the process terminated when a desired degree of coupling is obtained.
Thus, according to an exemplary method illustrated in FIGS. 9 and 10, a pair of fibers 91, 92 are threaded into the bore of a silica tube 93. The fibers 91, 92 are preferably the D-shaped fibers of FIG. 2 and are inserted into the tube 113 with the flat surfaces of the D's facing each other. The bore of the silica tube 93 is just slightly greater in diameter than the diameter of the combined pair of fibers so that the guiding regions of the fibers 91, 92 are automatically aligned when the fibers are inserted into the tube 93. Alternatively, the pair of fibers 91, 92 may be aligned and tacked together at an intermediate location by an electric arc so that alignment will be provided by the tacking rather than relying solely on a close fit between the fibers and the bore of the silica tube 93. The end portions of the silica tube 93 are then clamped into a miniature pulling machine generally designated 100 in FIGS. 11 and 12.
The pulling machine 100 is comprised of a linear slide base 101 receiving a block 102 fixed to the base, and a sliding block 103 also received by the base. The slide base 101 and blocks 102, 103 are optical bench components. One end portion of the silica tube 93 is clamped to the fixed block 102 and the other end portion is clamped to the sliding block 103. The linear motion of the sliding block 103 with respect to the fixed block 102 is limited by a stop 105 fastened to the fixed block cooperating with a micrometer 104 fixed to the sliding block. Thus, after the end portions of the silica tube 103 are clamped between the blocks 102, 103, the gap between the micrometer 104 pole face and the cooperating surface of the stop 105 may be adjusted to set the degree of extension of the silica tube 93 when it is drawn. The drawing tension is regulated by a spring 106 and is further set by a weight 107 strung over a pulley 108.
The drawing of the silica tube 93 occur when it is heated to the softening point by a platinum coil 109 which is energized by a power supply 110. The cross-sectional area of the tube 93 decreases as it is drawn, thereby closing in on and squeezing the D fibers together The coefficient of coupling between the optical fibers 91, 92 is monitored during the drawing process by exciting an input port A of the coupler with a laser 111 and measuring the response at output ports C and D with a photodetector 112. The apparatus shown in FIGS. 11 and 12 is semiautomatic, it being understood that the drawing process may be repeated a number of times while the coefficient of coupling is monitored until the desired coefficient of coupling is obtained.
while the method shown and described in conjunction with FIGS. 9-12 uses D-shaped fibers to form a directional coupler, it should be understood that other off-center core optical fibers may be coupled using this technique. To accommodation off-center core fiber having an arbitrary external cross-section, the cores may be first positioned together and then tacked. If an off-center core fiber is used which has a relatively large spacing between the outer surface of the fiber and the core, the portions of the fibers to be coupled should first be etched to expose the guiding regions on the fiber surfaces closest to the guiding regions.
The method of fabricating directional couplers illustrated in FIGS. 9-12 results in a unitary assembly wherein the fibers 61, 62 and the silica glass tube 63 are fused together at an intermediate location. In contrast to the design of FIG. 5, the unitary directional coupler is more suited for applications such as the fiber gyro which require the coefficient of coupling to be stable over long periods of time and also insensitive to mechanical shocks and other environmental stresses.
In accordance with one particular aspect of the present invention, the polarization-holding, single-mode optical fiber is used in a fiber-optic rotation sensor such as the laser/fiber gyroscope illustrated in FIG. 13. In this device optical signals are fed through a sensing coil 100 formed by winding a D-shaped fiber of the type described above around a cylindrical substrate 101. The fiber 100 and the substrate 101 preferably have similar coefficients of thermal expansion. A laser 102 supplies an optical signal which is launched into one end of the fiber used to form the sensing coil 100, and a directional coupler 103 splits the optical signal from the laser 102 so that it is propagated through the sensing coil 100 simultaneously in opposite directions. The optical signals emerging from both ends of the sensing coil 100 are passed through the coupler 103 to a photodetector 104 which compares the phase of the two light signals. The phase difference between the two signals is then used to determine the angular velocity and/or the angular acceleration of the entire sensor. The diameter of the coil and the number of turns determine the sensitivity of the gyro.
In keeping with the invention, a single length of optical fiber is used to form the illustrative gyroscope. Portions of this fiber (1) between the laser source 102 and a first end of the sensing coil 100 and (2) between the photodetector 104 and the second end of the sensing coil 100, are joined to form a directional coupler of the type described above. This directional coupler couples part of the signal from the laser 102 into the first end of the sensing coil 100, and it also couples part of the signal emerging from that first end of the coil into the photodetector 104. The signal emerging from the second end of the sensing coil 100 is transmitted directly to the photodetector 104, via the coupler 103. With this arrangement, only a single optical fiber and a single directional coupler are required, thereby greatly simplifying the construction of the gyroscope and minimizing its cost.
As a further feature of the invention, the sensing coil 100 is formed by winding the D-shaped fiber on the cylindrical substrate 101 with the flat surface of the D-shaped cross section engaging the substrate surface. This maintains a constant geometric relationship between the core of the fiber in the sensing coil and the surface of the substrate, thereby accurately locating the birefringent axes of the fiber relative to the fiber core and the substrate. The curvature of the fiber wound around the cylindrical substrate 101 to form the sensing coil 100 normally introduces stress birefringence in the fiber. If uncontrolled, this stress birefringence can add to the fiber birefringence to produce a resultant which is not in line with the axis of the fiber birefringence. With the arrangement of this invention, however, the axes of the stress birefringence and the fiber can be accurately aligned so that the stress birefringence merely adds to or subtracts from the fiber birefringence, without producing a resultant with a different direction. The axes of the birefringences are accurately located along the entire length of the coiled fiber, because there is no twisting of the fiber thereby providing excellent polarization-holding properties.
In addition to accurately locating the axes of birefringence, the winding of the flat side of the coiled fiber 100 on the substrate surface forms a coil with a precisely known path length. There is no twisting of the fiber along the length of the coil, and a constant distance is maintained between the substrate surface and the fiber core along the entire length of the coiled fiber. Consequently, the phase difference between the two signals propagated in opposite directions through the sensing coil 100 can be used to determine the angular velocity and/or the angular acceleration with a high degree of precision.
Yet another feature of the laser/fiber gyroscope of this invention is the coupling of the laser source 102 to the end of the fiber with the non-circular outer surface of the fiber forming a reference surface for precisely aligning one of the transverse orthogonal axes of the fiber core with the fixed polarization plane of the optical signal from the laser source. The laser source 102 is preferably a solid state, single-longitudinal-mode laser. The output of such a laser is normally polarized along the plane of the junction and will therefore launch the dominant 0 HE11 in the elliptical core of the fiber, i.e., the mode having the electric field along the major axis of the ellipse. A reference surface parallel to the laser junction may be formed on one side of the junction, so that when the flat surface of the optical fiber is placed on that reference surface and butted against the junction of the laser, the laser junction will be precisely aligned with the major axis of the elliptical core of the fiber. Thus, the connection of the fiber to the laser can be made simply and accurately, and the direction of polarization of the optical signal is accurately located with reference to the axes of birefringence of the fiber as the signal is launched from the laser into the optical fiber.

ST. LOUIS About the time Shane Robinson's bags were landing in Atlanta, he was arriving back in St. Louis to rejoin the Cardinals after a two-day absence. Robinson, sent to AAA Memphis on Sunday when Lance Berkman was activated from the disabled list, was recalled Tuesday morning when the club placed outfielder Jon Jay on the disabled list with a sprained right shoulder. So the outfielder packed his bags and flew to St. Louis in time for Tuesday's afternoon tilt at Busch Stadium against the Chicago Cubs. But he soon realized his bags weren't on the same flight. A mishap with Delta caused his bags one with his personal clothing and one with his glove, bats and other baseball gear to be put on a flight for Atlanta instead of his for St. Louis. So if he gets in Tuesday game, he'll have to borrow a teammates glove. "I'll have to walk around and see which one feels as close to mine," Robinson said Tuesday morning. "I'll have to see if they are nice enough to let me borrow it." R...

Hella expands radar sensor business by acquiring stake in Innosent
With more than 13 years of experience in the development and series production of modern radar technology, Innosent is a market leader in both the automotive sector and industrial applications. The scope of application for its products ranges from front and rear automotive applications. In addition, sensors are used in traffic monitoring applications. The cooperation will initially be focused on the development and production of radar sensors for applications in Hella's global network, the company said.
Hella integrates the 24 GHz radar sensor into various driving assistance systems, such as the lane change assistant. Christian Amsel, member of the executive board for the Electronics division, stresses the importance of radar sensors in the automotive industry: "The ever-increasing number of vehicles demands new means of monitoring traffic areas. Radar-based driving assistance systems such as the lane change and blind spot assistants help to improve road traffic safety. In emerging markets, too, the issue of safety is becoming increasingly important. The 24 GHz radar technology used by Hella is much cheaper than camera systems or 77 GHz radar systems, for example. As such, this system can also be used in the medium and low-range vehicle segments." In addition, Amsel said that the intensification of the business relationship will also help generate further growth areas, which in future will also allow the companies to supply the market for driving assistance systems with advanced technology in higher frequency ranges such as 61, 77 and 122 GHz - a field in which Innosent already has rich expertise
In addition to improving their position in the automotive sector, both companies are also pushing the further development of industrial applications: "Hella's contribution will allow Innosent to establish a secure foothold in the automotive sector. New technologies and applications can now be brought to market much more quickly. Furthermore, we see synergy effects between automotive technology and industrial applications not as chance, but as a core growth philosophy for the still relatively new radar sensor market," said Innosent co-founder Wolfgang Weidmann.
Hella has taken a share of 50 percent of Innosent. The move however is subject to approval by the antitrust authorities.

The advantage of flash technology for powering fast big data transactions is highlighted in a new, independent NoSQL database benchmark report from Thumbtack Technology. Aerospike today announced that the Thumbtack benchmark results revealed a nearly 10x performance advantage for the Aerospike database running on a combination of native flash and DRAM over two other NoSQL databases running on a mix of DRAM and RAM: Apache Cassandra and 10gen MongoDB. Aerospike is making reprints of the Thumbtack report, "Ultra-High Performance NoSQL Benchmarking: Analyzing Durability and Performance Tradeoffs," available at www.aerospike.com/benchmark.
"Our goal with the study was to determine which key-value store is most appropriate in a real-world scenario. That meant not only using raw hardware and solid-state drives, but configuring each database to optimally handle the workload," said Ben Engber, Thumbtack Technology CEO and co-author of the benchmark study. "Aerospike was the only vendor among those tested that specifically optimizes its platform around SSDs, so the Aerospike database's superior performance was not unexpected."
Benchmark Overview
Thumbtack evaluated the three NoSQL database and key-value store offerings using the Yahoo Cloud Serving Benchmark (YCSB) as the basis for the testing. To gauge their capacity and speed in handling big data while operating against disk, Thumbtack tested the databases' ability to process 500 million records. A fourth database, the Couchbase Server, was dropped from this evaluation because it could not load all of the records.
In the Thumbtack benchmark measuring a read-heavy workload, Aerospike achieved a maximum throughput of more than 300,000 operations per second, nearly 10x faster than its nearest competitor, Cassandra. For the balanced workload benchmark, Aerospike was 5x faster than Cassandra. In both tests, MongoDB placed third. The Thumbtack report notes, "This was particularly impressive since both Cassandra and MongoDB were using weak consistency models (returning success after only one copy has been written) and Aerospike was using a strong consistency model."
Across all four Thumbtack tests for latency, Aerospike maintained sub-millisecond latency even while processing 180,000 to 400,000 operations per second. Latency for Cassandra ranged from sub-millisecond to 8 milliseconds, and for MongoDB, it varied from 1 to 20 milliseconds; meanwhile neither database exceeded 40,000 operations per second.
The Flash-based SSD Advantage
"From the start, we recognized that a database optimized for both flash and DRAM would be ideal for emerging classes of applications that live or die by their ability to reliably respond within milliseconds," said Brian Bulkowski, Aerospike founder and CTO. "Today our customers rely on our native flash Aerospike database to achieve both the real-time responses and 100% uptime that this extremely high performance enables. Now the ThumbTack benchmark adds significant new validation of the value in optimizing databases and applications for SSDs."
"Providing fast reliable access to data in real-time is simple to say, but it's not easy to do," said Patrick DeAngelis, [x+1] CTO. "However, running our Aerospike clusters on SSDs, we've seen the database scale to a few billion key values with no compromise to performance, and we've even seen response times under 1 millisecond, which is phenomenal. We are now rethinking the way we store and access our data and intelligence because of the options that Aerospike gives us."
"We continue to push the boundaries of what you can do in a real-time environment, and Aerospike's architecture, which is optimized for flash storage, means we can be a lot more efficient with the way we spread our data," said Mazdak Rezvani, Chango CTO. "Already we've seen a 25% improvement in efficiency with Aerospike over our previous NoSQL database."
Complementing Thumbtack's NoSQL benchmark is the Aerospike Certification Tool (ACT) for benchmarking the ability of SSDs to support database transactions. ACT, which Aerospike has made available as open source software, can be downloaded at http://github.com/aerospike/act. In December 2012, Aerospike published the ACT benchmark results for several SSD models from Fusion-io, Intel, OCZ, and Samsung. These results can be viewed at http://www.aerospike.com/blog/act-ssd-benchmark.

17th Cloud Expo, taking place Nov 3-5, 2015, at the Santa Clara Convention Center in Santa Clara, CA, will feature technical sessions from a rock star conference faculty and the leading industry players in the world. Cloud computing is now being embraced by a majority of enterprises of all sizes. Yesterday's debate about public vs. private has transformed into the reality of hybrid cloud: a recent survey shows that 74% of enterprises have a hybrid cloud strategy. Meanwhile, 94% of enterprises are using some form of XaaS – software, platform, and infrastructure as a service.

The Sandzak Divided: Language and Identity Politics on Either Side of the New Serbian/Montenegrin Border
March 28, 2013 // 12:00pm — 1:00pm
Global Europe Program
In the post-Yugoslav context, members of these Muslim communities have largely self-identified as Bosniaks, an ethnic/national term that gained prominence among Bosnian Muslims in the period immediately following the dissolution of Yugoslavia in 1991 and the outbreak of the war in Bosnia-Herzegovina. While language policies in this region were centrally formulated in the joint state, with the dissolution of the Republic of Serbia and Montenegro in 2006, the two halves of the Sandžak experienced divergent language policies. In his presentation, Robert Greenberg, professor of linguistics at the University of Auckland in New Zealand, argues that the division of the Sandžak may have been a catalyst for destabilizing and radicalized forces to emerge in the years following the formal Serbia/Montenegro split.

Taiwan and the U.S. Pivot to Asia: New Realities in the Region?
February 26, 2013 // 3:30pm — 5:30pm
Asia Program
As the United States rebalances its diplomatic and military focus toward Asia, some analysts have voiced concern about what a greater U.S. presence in the region might mean for cross-Strait relations. While ties between China and Taiwan have improved in recent years, will the U.S. pivot toward Asia shape the further evolution of cross-Strait relations? Will other Taiwanese interests be impacted by the rebalance? Could Chinese uneasiness about the rebalance work to Taiwan's detriment? From Washington's perspective, how does Taiwan fit into the pivot?

well the fact is the universe has been around longer than planets like the earth. Given the universe is 10billion years older than the earth, i am sure it would have somewhere spawned planets like earth billions of years before this planet even existed. Given the low probability of protein forming, well, its happened once in 1 billion years (time it took for first simple cells to form) in earth conditions, so we know it must have occured at least a few more times in 10 billion years before the earth has even existed. Given the number of earth like planets out there each Billion years there is a chance of prokaryotes forming. If it did happen and then that civilization is billions of years more advanced than us, they probably have control over space and time, i doubt they would have any interest in a noob civilisation like ours. Instead they would probably be not wanting to wait a billion years for an evolutionary event to take place, instead they might just be dumping cells here and there and watching the result or having their machines do it. So if this is happenening theres alot more life out there :) rather than aliens just leaving it to chance. :)) So cmon, if you were the most advanced civilisation in the universe, what else would you be doing? Playing God of course :)
Someone is shy
Van hasn't completed a profile. Should we look for some other people?

Its cool you are offering this open source, not like many people who would get thousands of patents and block everyone from innovating on your ideas
Looks like you have spent all your time applying for patents, 414. If you really wanted to save lives you would be just mass producing this stuff and not give care too much about people who want to copy your idea, because that will only save lives too, who knows, they might even do a better job at distributing and selling it that you. But instead you chose the path of cock blocking everyone else from being able to quickly market similar items. So the reality is, you have now killed more people with your patents by not letting other people create similar products to take to market sooner and better than yours. Don't hide behind the veil of you are doing good. All you did is get a good idea that will save lives, and patent the crap out of it, now no other company can do a similar thing, hence you actually killed way more people and profit off the death of people who can't access this product only made by you, actually are you busy mass producing this? impossible, still in court patent whoring and money mongering. So you and a bunch of friends came up with idea? 414 patents later? i guess all your friends were lawyers. 3 years on, people are still dying because they don't want to infringe on your patents. SOB. And this product still is not on the shelf here in Australia anyway

OUR HOUSE - The Madness Musical
by arrangement with Josef Weinberger Ltd
By Tim Firth with Music and Lyrics by MADNESS
at The Bradford Playhouse 3rd June to 6th June 2015
Tickets now on Sale
Inspired by the music of Madness, this raucous musical comedy is an uplifting tale of life and love, heartbreak and hilarity, good and bad, set in London's famous Camden Town in the mid-80s.
It's Joe Casey's 16th birthday and tonight's the night he's treating his girlfriend Sarah to an evening in a brand new luxury apartment – the only problem is he has to break in! When the police turn up Joe has to decide – run away, or face the music – a choice that will set the course of his life, and his love, forever.
Bringing together one of the most successful British writers with one of the best loved British bands, this new actor-musician production will have you laughing, crying and dancing in the aisles.
Using some of the greatest hits from the mighty Madness back catalogue including: Our House, Baggy Trousers, My Girl, Driving in My Car, The Wings of a Dove, Night Boat to Cairo and the all-time classic It Must Be Love – you'd be mad to miss it!
Our House is written by Tim Firth whose work includes the record-breaking Calendar Girls, Kinky Boots, Preston Front and Neville's Island.
Review of Oh What A Lovely War 22nd October 2014 by James McPherson
Briiliant. A superb ensemble show. Not to be missed. This is the only way I can describe The Bradford Players production of Oh What A Lovely War at The New Bradford Playhouse.
I had never seen the show before and wondered if it was right to present a show about war. I am very glad I saw Oh What A Lovely War. It is sensitively presented and an excellent way to remember with respect the people from all parts of the World who died in the First World War.
I laughed, cried,sang along with the songs and learnt a lot I did not know about the First World War . The show is a roller coast of emotions as it tells the story of the First World War and the people involved. Excellently directed, first class choreography and a superb band that does not drown out the singing. The ending is one of the most emotional I have seen in any show.
I had two little concerns which, from comments I heard, were shared by other members of the audience. During the First Act it was hard to read the information that was projected onto a curtain which did spoil the effect. Second, I would have loved to have been able to properly applaud the cast and the band at the end. Perhaps the cast could have returned to the stage after a few moments to take a bow. Having said that this is a show not to be missed.
Oh What A Lovely War runs until Saturday night and is well worth seeing.

Small Changes Rated 4 out of 5 stars
Thx for the add-on, really useful. I was looking for some time now for a second "new tab" button for ff4. I like to have one next to the tabs and the second next to the bookmarks button. Nevertheless I change two this
1. After clicking the button it should open "about:blank" - This way it will work perfectly with the "Fast Dial" add-on
2. Change the icon for a simple + , just like the original "new tab" button. It would compose better
Nevertheless, great Job.

Is there any other approach to achieve this? Without invoking a new URL, when I click the button in iPad, can I somehow login to the web application (in iPad's browser) and show the page in the browser?

Health insurance helps defray the cost of routine, preventative medicine as well as catastrophic illness or injury expenses. In contrast, discount medical plans provide subscribers with a network of healthcare providers, pharmacies, and other health-related services from whom they can receive discounted rates on things like medical screenings, eye exams, dental care, and prescription medications. These plans are not healthcare coverage, but more like a network of providers who agree to provide discounts to members of specific plans. The providers get access to more customers without marketing, in exchange for offering discounts. « less Published April 25, 2013 16 views More Info » Full Credits careultima8 Uploader Stats & Data 0 Funny Votes 0 Die Votes 16 Views Published April 25, 2013 Categories: Real Life Keywords: California Medical Card illinois medical card colorado medical card arizona medical card washington medical card oregon medical card kentucky medical card ohio medical card texas medical card west virginia medical card louisiana medical card hawaii medical card missouri medical card Up Next: Boxing Cat AUTOPLAY Up Next In: 10 Boxing Cat Show Off Fail HOW TO FIGHT Parking Spot WIN Follow Facebook Twitter Tumblr Instagram Browse Related Comments Vaguely Related Videos Vaguely Related Pics & Words Advertisement Advertisement From Around the Web ZergNet
