Optical-fiber media for squeezed-state generation

The Kerr nonlinearity characteristic of optical fibers produces squeezed states of light by a mechanism that differs from conventional four-wave mixing. The noise sources characteristic of such a medium also have a unique character. We present a unified picture of these interactions for both traveling-wave and cavity geometries. Results of experiments on squeezing in optical fibers and fiber ring resonators are discussed and compared with the theory. © 1987, Optical Society of America.
