摘要：

We study solitary wave solutions of the higher order nonlinear Schrodinger equation for the propagation of short light pulses in an optical fiber. Using a scaling transformation we reduce the equation to a two-parameter canonical form. Solitary wave (l-soliton) solutions always exist provided easily met inequality constraints on the parameters in the equation are satisfied. Conditions for the existence of N-soliton solutions (N greater than or equal to 2) are determined; when these conditions are met the equation becomes the modified Korteweg-de Vries equation. A proper subset of these conditions meet the Painleve plausibility conditions for integrability.
