An efficient and automated finite‐element package (named WAVEGIDE), which is implemented within the PDE/Protran TM problem‐solving environment, is extended here to the analysis of two‐dimensional nonlinear optical waveguiding structures. With WAVEGIDE, through an interactive question‐and‐answer session, which requires modest knowledge of programming and minimal effort for the input of waveguide parameters, the problem can be defined using high‐level PDE/Protran TM commands. To illustrate the ease of use, flexibility, and accuracy of the developed package, numerical results for the first quasi‐TE power‐dependent mode in a buried nonlinear waveguide was presented. The program is available in the public domain. © 1994 John Wiley & Sons, Inc.
