The above fabricated waveguides were characterized using a Picoquant continuum laser. Concisely, a continuous wave Ti-Sapphire laser (Laser Quantum ventus 532 nm from Lastek Photonics Technology Solutions) has been used as a light source to evaluate the transmittance by recording the laser emission transmission directly from the straight edge of a waveguide, while waveguide emission was collected from the angular edge of the waveguide. The beam reaches the sample stage through an optical fiber with a diameter of 1.1 mm. Firstly, the emission fluency of continuous laser has been measured at 532 nm (0.33 mW) using a calibrated Thorlabs photodetector (S/N: 220303150) with a detection wavelength limit ranging between 200 nm and 1100 nm and maximum fluency detection upto 50 mW. The power of total emitted photons sensed by calibrated photodetector has been recorded using Thorlabs PM100D handheld optical power and energy meter. The transmittance values have been computed by dividing the angular waveguide light power by directly transmitted light.
