Paper Abstract

Pulse propagation in the presence of spectral filtering, two-photon absorption, linear and nonlinear gain is investigated both for anomalous and normal dispersion regime. We analyze the steady-state pulse propagation in such a system and we observe that both the soliton chirp and width are significantly larger for normal than for anomalous dispersion. An unexpected singularity of the soliton amplitude and its width is observed in the anomalous dispersion regime when the net linear gain vanishes. We also show that arbitrary-amplitude solitons can propagate in this dispersion regime for a given relation between spectral filtering, nonlinear gain and two-photon absorption.
