Polarization may be an interesting parameter in optical computing devices. Polarization induced irradiance switching was proposed as a new switching mechanism in nonlinear Fabry-Perot NLFP etalons under oblique incidence. In this context, the stationary response of Fabry-Perot etalons containing an anisotropic medium exhibiting a diffusive Kerr-type nonlinearity was investigated. Here, we will address the question of the influence of polarization on the response of a nonlinear prism coupler NLPC, where the waveguide shows a diffusive third order nonlinearity. Prism coupling of light into integrated nonlinear optical waveguides has been the subject of extensive theoretical and experimental investigation over the past few years. It is established that in the case of a diffusive nonlinearity, both plane wave and finite beam calculations yield a bistable optical response in good agreement with the experimental observations.
