Nonlinear dispersion effects in the low-noise properties of squeezed light in transmission chains formed from nonlinear alternating attenuators and amplifiers
Abstract
An idealized model of an optical communication link in which identical sections of nonlinear attenuating fiber alternate with identical optical amplifiers is considered. Signal-to-noise ratios of chains of these elements for input squeezed and coherent light have been numerically evaluated, taking into account the deleterious effects due to nonlinear dispersion. It has been previously shown that input squeezed light and nonlinear attenuators improve the signal-to-noise ratios with respect to coherent inputs and linear chains. It is shown here that nonlinear dispersion degrades the signal-to-noise ratios, but the coherent input is more appreciably degraded than the squeezed input.
