Pulse-pulse Interaction in Dispersion-managed Fiber Systems with Nonlinear Amplifiers

Abstract

The pulse-pulse interaction in a dispersion-managed fiber system is studied for the case when a nonlinear gain and spectral filtering are included into the dispersion-gain map. In this system, the pulse of any shape converges quickly to a dispersion-managed soliton. Using the technique of interaction plane, we have found stable bound states of two pulses. The effects we have studied may significantly reduce the chances of pulse coalescence in specially designed optical transmission lines.
