We investigate numerically, both in time and frequency domains, the influence of some higher-order effects, namely the third-order dispersion, intrapulse Raman scattering, and self-steepening, on the dynamics of different pulsating and chaotic solitons in dissipative systems, which are described by a generalized complex Ginzburg-Landau equation. We show that the higher-order effects can have a dramatic impact on the dynamics of such pulses and that, for some ranges of the parameter values, they can be transformed into fixed-shape solitons.
This paper is dedicated to Prof. Helmut Brand on the occasion of his 60th birthday.
