Energy-exchange collision of the Manakov vector solitons under strong environmental perturbations

subject

description

International audience; We use a collective-variable approach to study the dynamical behavior of vector solitons in the Manakov system under strong environmental perturbations induced by the fiber losses and a modified cross-phase modulation parameter. We identify and discuss the salient features associated with energy-exchange collisions of transmissional and reflectional types. Particularly, we find that such perturbations can induce important effects not only on fundamental soliton parameters such as the peak power, central position, width, chirp, and frequency, but also on the nature of the collision. Interestingly, we find that the perturbations lead to only a slight alteration of collision-induced energy-switching processes. A property of high robustness of the energyexchange collision of the Manakov vector solitons is thus demonstrated.
