| Popis: | Localized structures in optics have attracted attention for their potential applications in tele- communications and information storage. In the present work, localized structures with non-uniform phase structure in the degenerate optical parametrical oscillator are reported and elucidated. Dissipative solitons with non-uniform phase structures in parametrically driven systems have been already observed in prototype models being found in two typical shapes: symmetrical and asymmetrical. In contrast, the phase structure in degenerate optical parametrical oscillator is always symmetrical, showing a pro- nounced bell-shaped phase. We show that the nonlinear saturation present in this physical system is responsible of a relaxation dynamics and this symmetry. Probing that real physical systems exhibit al- ways this unique type of localized structure with phase structure. An adequate analytical description for the phase, based on a simple model, is achieved showing that such structure is controlled by the in- terplay between the detuning, the external pump and the losses of the cavity. Numerical simulations present quite agreement with theoretical predictions. |
