Paper Abstract

We present an improved method for estimating the dark count rate of single-photon-sensitive avalanche photodiodes (SPADs) with either InP or InAlAs multiplication layers. Our simulation of junction breakdown probability can easily accommodate arbitrary electric field profiles and APD bias conditions. In combination with local models of dark carrier generation, our technique can provide more realistic estimates of dark count rate than are obtained by multiplying the primary dark current by a single junction breakdown probability, or by assuming constant electric fields in the multiplication layer. Our method can assist in the design of SPADs for demanding laser radar applications.
