Abstract

A numerical simulation technique to study the propagation of pulses in nonlinear waveguides (NLWG) with materials that exhibit Kerr or non-Kerr nonlinearities with finite time response is presented. This method is a combination of the split-step finite element method and a third-order accurate difference scheme to match the solution along the characteristic of the (z,t) plane. The simultaneous effects of integrating and higher-order nonlinearity on the stability of pulses in nonlinear waveguide structures have been examined.
