Abstract :
The optimization of a waveguide photodiode (WGPD) having a thin absorption layer is discussed. Responsivity of 1.09 A/W was achieved. More than 100 A thick absorption layer is required for high responsivity and low polarization dependency. A formula for frequency response in a WGPD with a thin absorption layer is obtained.
