Generation and Dynamics of Dissipative Optical Cavity Soliton

Abstract

Optical dissipative solitons, namely, cavity solitons have been investigated in different dissipative media, particularly, in vertical cavity surface emitting laser (VCSEL) cavity with different feedback configuration. For first time super Gaussian and Cosh-Gaussian type cavity solitons have been achieved. Models based on Cubic Ginzburg-Landau equations have been solved by separation method with Super Gaussian profile with and without feedback. Cosh- Gaussian cavity soliton has also been found in VCSEL with saturable absorber and frequency selective feedback. The range of parameters that promise cavity solitons has been identified. As a special case, a large continuous family of Cosh- Gaussian cavity solitons has been found that apparently resembles with conservative solitons. Cosh- Gaussian cavity solitons thus found are of versatile profile and will be of fundamental and applied research interest. The cavity solitons achieved by this investigation have huge potential applications in all optical devices, like all-optical erasable memory device, all-optical data storage, delay lines, all-optical push broom and multi-level logic systems.
