The propagation characteristics of nonlinear guided waves along a nonlinear waveguide bounded by two identical self‐focusing media

Abstract

The propagation phenomena of nonlinear guided waves along a nonlinear waveguide bounded by two identical self‐focusing media are studied numerically. Both TE0 and TE1 guided waves are investigated. It is indicated that the derivative of the guided‐wave power flow with respect to the guided‐wave effective index can be a criterion for the stability of nonlinear guided waves under consideration. © 1993 John Wiley & sons, Inc.
