Title: Periodic solutions of the complex cubic-quintic Ginzburg-Landau equation in the presence of higher-order effects
Keywords: nonlinear fiber optics, Ginzburg-Landau equation, dissipative solitons

Abstract: We have studied numerically the influence of intrapulse Raman scattering (IRS) and self-steepening (SS) on the period - 2 pulsating solution of the complex cubic-quintic Ginzburg-Landau equation (CCQGLE). A cascade of transformations of the numeric solutions under the influence of SS is reported, which includes the existence of: period - 1solutions, chaotic solutions, period–doubling transformation leading to the appearance of pulsating solutions with many periods, then period–halved transformation, periodic in t and x solutions and, finally, uniformly translating fronts. We have shown that by increasing the IRS parameter, the period- 4 pulsating solution related to the SS can be successfully transformed into a period-2, period-1 pulsating solutions and, finally, into a stationary solution.
