Convection-induced stabilization of optical dissipative solitons
Résumé
In spatially extended convective systems, the reflection symmetry breaking induced by drift effects leads to a strik- ing nonlinear effect that drastically affects the formation and stability of dissipative solitons in optical parametric oscillators. The phenomenon of nonlinear-induced convection dynamics is revealed using a model of the complex quintic Ginzburg-Landau equation with nonlinear gradient terms in it. Mechanisms leading to stabilization of dissipative solitons by convection are singled out. The predictions are in very good agreement with numerical solu- tions found from the governing equations of the optical parametric oscillators.
