Abstract :
In this paper a physical model for waveguide-separated absorption charge multiplication avalanche photodetector (WG-SACM-APD) is presented. Through some straight forward manipulations and considering the theory of linear time invariant system, frequency domain modeling of this detector including parasitic sources is achieved. Finally, the transfer function and detector´s bandwidth with respect to the multiplication gain are also investigated.
