Abstract

A particularly fascinating and promising class of optical switching structures is attracting widespread attention. These use nonlinear optical materials in fiber or integrated optical geometry.¹ While the development of this field will drive research into strongly nonlinear materials, it also emphasizes a need for accurate and rigorous computer-modeling techniques. Although such techniques are already well established in microwaves and in the analysis of linear optical waveguides and devices,^2-4 the study of nonlinear optical phenomena poses some different problems requiring very sophisticated numerical methods.
