Conversion of Poisson Photons into Sub-Poisson Photons by the Action of Electron Feedback

Poisson photons may be converted into sub-Poisson (amplitude-squeezed) photons by the action of an electron current configured in an external feedback loop. The generation mechanism involves single-photon transitions so that the source can be made arbitrarily sub-Poissonian. Non-linear optics is not invoked. A useful configuration involves a photon emitter illuminating a detector-source combination in a closed-loop system. Two solid-state implementations of the detector-source combination are suggested.
