Dissipative Raman solitons

Opt Express. 2014 Dec 1;22(24):30118-26. doi: 10.1364/OE.22.030118.

Abstract

A new type of dissipative solitons--dissipative Raman solitons--are revealed on the basis of numerical study of the generalized complex nonlinear Ginzburg-Landau equation. The stimulated Raman scattering significantly affects the energy scalability of the dissipative solitons, causing splitting to multiple pulses. We show, that an appropriate increase of the group-delay dispersion can suppress the multipulsing instability due to formation of the dissipative Raman soliton, which is chirped, has a Stokes-shifted spectrum, and chaotic modulation on its trailing edge. The strong perturbation of a soliton envelope caused by the stimulated Raman scattering confines the energy scalability preventing the so-called dissipative soliton resonance. We show, that in practical implementations, a spectral filter can extend the stability regions of high-energy pulses.
