Stochastic perturbation of sub-pico second envelope solitons for Triki–Biswas equation with multi-photon absorption and bandpass filters

Abstract

This paper studies sub-pico second solitons modeled by Triki–Biswas equation that is a generalized version of Kaup–Newell equation in presence of stochastic perturbation terms, in addition to deterministic perturbations which are due to multi-photon absorption and bandpass filters. The soliton mean free velocity is recovered after analyzing the corresponding Langevin equation.
