Excess Noise Correlation Using Population-Trapped Atoms

摘要

We study the behavior of two quantized fields interacting with atoms in acoherent population-trapped state. It has recently been shown that such a system generates fields with matched envelopes as well as matched photon statistics. These effects have an important consequency: the matching of any excess noise input at the two channels of the system. We explicitly show the generation of correlated excess noise by a population-trapped atomic system and how this effect may be used to suppress the excess noise and enhance the carrier-to-noise ratio of optical sources.
