A numerical method for analysis of waveguide-separated absorption charge multiplication-avalanche photodetector(WG-SACM-APD)

In this paper a numerical method for analysis of waveguide-separated absorption charge multiplication avalanche photodetector (WG-SACM-APD) is presented. Considering the theory of Taylor series, frequency domain modeling of this detector including parasitic sources is achieved. Finally, the detector's transfer function and bandwidth with respect to the multiplication gain are also investigated.
