Abstract :
We present an equivalent circuit model for 1.55-μm germanium waveguide vertical photo detector on a Si-on-Insulator (SOI) substrate. The model has two current sources for modeling photogenerated carriers so that those carriers experiencing drift and diffusion within the Ge intrinsic layer can be independently modeled. The model provides photo detection frequency response simulation results that match very well with the measurement results. It should be very useful for designing integrated Si optical receiver.
