Abstract

In recent years, all-optical devices have attracted much attention both in theoretical studies and experimental varifications. After the experimental observation of soliton and their interactions in glass planar waveguide by J.S. Aitchison, A.M. Weiner, Y. Silberberg, etc.[1] in 1991, optical switches using spatial optical solitons have been proposed by several authors[2,3]. Since all types of nonlinear optical material exhibit some losses, the loss factor should be included in device designs and analyses. The loss factor is especially critical in devices using material with small nonlinear coefficient since it requires high threshold power to excite solitons in the material.
