Quasi-stationary optical Gaussons

Abstract

This paper studies the dynamics of optical solitons with log law nonlinearity, also known as optical Gaussons, in the presence of perturbation terms. The multiple-scale perturbation analysis is applied to obtain the quasi-stationary optical Gaussons solution. The definition of the phase that is introduced in this paper reveals a couple of resonant conditions that cannot be otherwise recovered. A numerical simulation is also included.
