Abstract :
A photodetector can be applied onto the silicon-on-insulator waveguide tap to monitor light signals on waveguide for the surface mount detection. The reflective metal layer integrated with 54.7-degree angles from anisotropic silicon wet-etching demonstrated low polarization-dependent-loss of 0.2 dB.
