Abstract
Numerous schemes have been recently suggested for generating photon-number-squeezed light. In one class of technique, initially Poisson photons are modified (using methods such as deadtime deletion, decimation, coincidence decimation, and overflow count deletion) to yield sub-Poisson photons. In another class, feedback is applied (e.g., by control of the rate of generation of photoevents) so that the resultant point process is self-exciting instead of Poisson. Are such light sources useful for optical communication? Can the channel capacity C of a lightwave communication system based on photoevent point process observations be increased by use of photon-number-squeezed light?
