Silicon CMOS interdigitated-MSM photodetector and self-mixer for low-cost crash-avoidance Ladar system

Abstract

We present theoretical model of interdigitated MSM photo-detector and RF electro-optic self-mixer based on standard CMOS technology. The model allows for simulation and analysis of photodetection performance and RF self-mixing capabilities of MSM. A performance comparison is performed between Si and GaAs materials in case of steady-state and transient operation.
