Optical Soliton Perturbation With Non-Kerr Law Nonlinearities

Abstract

Abstract-This paper studies solitons and its perturbations that is governed by the generalized nonlinear Schrödinger's equation with nonKerr law nonlinearity. The quasi-stationarity is applied to the non-Kerr law case and an approximate solution is obtained. A few special cases of the non-Kerr law nonlinearity are considered, as examples, with the nonlinear damping type perturbation.
