Abstract

Stationary TE-polarized nonlinear waves, guided by thin films that are bounded by nonlinear diffusive media, are studied numerically for a variety of waveguide structures. We calculate both the guided-wave power as a function of effective index and the power-dependent field distributions. The nonlinear guided-wave dispersion relations are found to move to higher powers with increased diffusion length. For an asymmetric waveguide composed of two nonlinear media with unequal diffusion lengths, we predict the existence of two distinct asymmetric solutions.
