Paper Abstract

A feature of metal-semiconductor-metal (MSM) photodetectors is their low capacitance. In this paper, a new design formula is presented for the capacitance per unit area of an MSM photodetector. A comprehensive circuit model is also described which incorporates the optoelectronic conversion within a larger model which in turn accommodates the transmission line effects of the interdigitated structure. These models can be used to optimize the design of a receiver employing an MSM photodetector.
