Dynamic of HNLS Solitons using Compact Split Step Padé Scheme

[摘要] In this communication, we use a compact split step Pade scheme (CSSPS) to solve the scalar higher-order nonlinear Schrodinger equation (HNLS) with higher-order linear and nonlinear effects. The second part, consisting of two sections, the first section is dedicated to the study numerically the stabilization of high-order solitons dynamic in optical fibers by compensation or by the interplay of higher order nonlinearity-especially quintic nonlinearity- and the self-steepening. In the second section we study also numerically the propagation of conventional chirped or unchirped solitons in optical fibers with to the management of the nonlinearity, dispersion and loss (gain).
