Abstract

Waveguide Photodetector (WGPDs) are considered leading candidates to overcome the bandwidth-efficiency trade-off presented in conventional photodetectors. In this paper, we present a physical model of the waveguide-separated absorption charge multiplication-avalanche photodetector (WG-SACM-APD). Both time and frequency modeling for this photodetector are presented. The frequency response has been simulated for different thicknesses of the absorption and multiplication layers and for different areas of the photodetector. The gain-bandwidth characteristic of WG-SACM-APD is studied for different areas and different thicknesses of both the absorption and the multiplication layers showing the dependence of the performance of the photodetector on the dimensions, the material parameters and the multiplication gain. In addition, the characteristics of WG-SACM-APD are studied for the case of an inductor added in series to the load resistor and better performance is achieved in comparison to the case with no inductor. The results obtained from the model that is presented in this work are compared with published experimental results and good agreement has been obtained.
