Abstract
The cutoff rate R0 of an optical channel transmitting M-ary phase-shift-keyed coherent states is calculated for a receiver using the optimum quantum detector. This is shown to be nearly equivalent, when M≫1, to a system that measures the phase of the received signal. A closed-form expression yielding a good approximation to R0 is derivedKeywords
