In telecommunications, a mode scrambler or mode mixer is a device for inducing mode coupling in an optical fiber, or a device that, itself, exhibits a uniform output intensity profile independent of the input mode volume or modal excitation condition.
In telecommunications, a mode scrambler or mode mixer is a device for inducing mode coupling in an optical fiber. An ideal mode scrambler creates a uniform output intensity profile across the fiber core independent of the input mode volume or modal excitation condition.
