Abstract

In this paper, the information rate of single photon avalanche diode (SPAD) receivers with active quenching circuits for optical communication systems is studied. The SPAD receiver is modeled as a discrete memoryless channel (DMC), and the information transfer rate is studied using an information theoretic approach. To assess the input-output information transfer rate of the SPAD optical receiver, a channel capacity metric is proposed which is a function of the physical parameters including average signal photon count, SPAD dead time, and SPAD average background counts. The proposed metric can be used for theoretical optimization of the device structure and operating conditions. Performance results are presented based on the proposed metric.
