Nonlinear thin-film guided waves in non-Kerr media

Abstract

The power-dependent wave vector is calculated for nonlinear waves guided by a thin film bounded by media whose dielectric constant varies as some arbitrary power of the optical field or saturates at high powers. The effect of such non-Kerr-like nonlinearities on the power-dependent wave vector and field distributions is given for a number of potential devices proposed earlier for Kerr-like media.
