Abstract

The combination of linear guiding and nonlinear self-guiding effects present in nonlinear waveguides lead to a variety of phenomena that are absent in linear wave guides. Of particular interest are thresholds in the power dispersion curves for nonlinear modes. These properties and others suggest that nonlinear waveguides may have many uses in optical signal processing. Most of the papers written to date^1-12 examine isotropic nonlinear guided waves. The inclusion of anisotropy^33-14 is often important because of the inherent strain near the interface between two dissimilar coherently grown crystals. This strain induces an anisotropy in the dielectric tensor. Because a single interface is the simplest guiding structure, it is the best starting place for investigations of new types of nonlinear guided waves.
