Finding Solitons in Bifurcations of Stationary Solutions of Complex Ginzburg–Landau Equation

Nonlinear dissipative systems, particularly optical dissipative solitons are well described by complex Ginzburg–Landau equation. Solutions of two-and three-dimensional complex cubic-quintic Ginzburg–Landau equation as-suming exponential dependence on propagation parameter are studied. Ap-proximate analytical stationary solutions of cubic-quintic Ginzburg–Landau equation are found by solving systems of ordinary differential equations. We are solving two-point boundary problems using adapted shooting method. Stable and unstable branches of the bifurcation diagram are identified using linear stability analysis. In this way we established conditions for generation and propagation of stable dissipative solitons in two and three dimensions. These results are in agreement with numerical simulation of cubic-quintic Ginzburg–Landau equation and the recently established approach based on variational method generalized to dissipative systems and therein established stability criterion.
