Kink Waves in an Extended Nonlinear Schrödinger Equation with Allowance for Stimulated Scattering and Nonlinear Dispersion

Abstract

We study the stationary wave solutions of an extended nonlinear Schrödinger equation with nonlinear dispersion and stimulated scattering. New classes of the kink waves with nonlinear phase modulation, the existence of which is stipulated by the balance of nonlinear dispersion and stimulated scattering, have been found.
