Split-Step Algorithm Based Propagation Modelling of Dark Soliton-Like Pulses

Abstract

Many methods exist to model light propagation in optical fibers. Recently, a new method called “split-step method,” based on the Fourier transform, has emerged. This method shows well the interplay between the dispersion and nonlinear effects in the optical fiber. We present here some results for this method applied to dark soliton-like pulses in normal dispersion regime.
