<title>Nonclassical-light generation in a photonic-band-gap nonlinear planar waveguide</title>

Abstract

Optical parametric process occurring in a photonic-band-gap planar waveguide is studied from the point of view of nonclassical-light generation. Nonlinearly interacting optical fields are described by the generalized superposition of coherent signals and noise using the method of quantum linear corrections to a classical strong mean-field' solution. Scattered back-propagating fields are taken into account. The possibility to generate squeezed light and light with sub-Poissonian statistics in dependence on the strength of scattering, strength of nonlinear interaction, linear and nonlinear phase mismatches as well as characteristics of the states of optical fields incident on the waveguide is discussed in detail.
