Description
Self-induced transparency (SIT) is a highly nonlinear effect in which a resonant (or near resonant) pulse of light propagates losslessly in a medium via a coherent cycle of absorption and stimulated emission. Here we study the use of SIT for creating squeezed states of light through both nonlinear phase-shifts (quadrature squeezing) and nonlinear absorption (amplitude squeezing). In particular, we model the propagation of optical pulses through a gas-filled hollow core fibre. This configuration allows interaction of intense pulse of light with an atomic medium over long distances, while at the same time avoiding the excess Raman noise that standard optical fibre imprints on optical pulses. Solving the quantum dynamics of the atomic and optical fields through well-tested stochastic approaches, we find substantial levels of quantum squeezing are obtained even in the presence of experimentally-relevant levels of decoherence.
