The author is concerned with the derivation and analysis of optimum demodulators for optical digital communication systems where several users modulate coherent light of the same frequency. The information transfer is represented by a discrete-input multiple-access channel which outputs a scalar conditionally Poisson point-process modeling an ideal photodetector counting process. The rate of the counting process put out by the photodetector is a function of the instantaneous incident power of the sum of the electric fields modulated by several active users. Arbitrary signal constellations and both asynchronous and symbol-epoch synchronous Poisson multiple-access channels of both additive-light and additive-rate types are considered.
