Abstract

Based on an extended method of multiple scales, an analytical description of the optical solitons in a model for the propagation of nonlinear pulses in dispersion-managed optical fibers is presented. The results show that the optical pulses can be expressed by quantummechanical wavefunctions of a linear oscillator, which have tails of Gaussian type, modulated by hyperbolic secant solitons of the nonlinear Schrödinger equation.
