Abstract

Interaction as well as dynamics of the dark-bright vector solitons induced by incorporation of gain and two-photon absorption are investigated by the numerical method in a birefringent fiber. The numerical results show that the gain and the two-photon absorption may lead to the destructive effects on the soliton propagation and interaction. Their combined effects play a crucial role in the dynamics and depend strictly on the sign and magnitude of their coefficients, so the proper incorporation may reduce effectively their destructive effects. The nonlinear gain combined with the filter can be used to suppress effectively the disadvantaged effects and the stabilization mechanism is demonstrated.

Keywords:

Combined effect, dark-bright vector soliton, gain, two-photon absorption,
