Optical soliton perturbation with time- and space-dependent dissipation (or gain) and nonlinear dispersion in Kerr and non-Kerr media

In this paper, based on the integrable idea, analytical solutions of the perturbed nonlinear Schrödinger equations in the presence of time- and space-dependent dissipation (or gain) and nonlinear dispersion with five types of nonlinearities are obtained. These nonlinearities are the Kerr law, power law, parabolic law, dual-power law as well as the log law.
