Abstract

The propagation of solitons through an optical fiber is governed by the nonlinear Schrödinger's equation. In general, the solitons in a non-Kerr law media is going to be addressed. The multiple-scale perturbation technique will be used to carry out the analysis. A new definition of the phase of the soliton will be introduced that will capture the corrections to the pulse where the standard soliton perturbation theory fails. The study will be conducted with nonlinear damping and saturable amplifiers which are going to be treated as perturbation terms.
