![عکس صفحه اول مقاله: Interactions of dark solitons in photovoltaic photorefractive crystals with diffusion nonlinearity Interactions of dark solitons in photovoltaic photorefractive crystals with diffusion nonlinearity](/preview/png/1538205.png)
We investigate the interaction of spatial dark optical soliton pair in open-circuit photovoltaic photorefractive crystals by considering the effect of background light and diffusion nonlinearity. We show that the spatial dark solitons repel each other and travel along different trajectories for the coherent interactions that one undergoes reflection and the other one deflects significantly when they are closely overlapped, and the dark solitons attract and deflect simultaneously along a parabolic trajectory for the case of incoherent interactions. The deflection distance depends on the intensities and the initial separation between the dark solitons.
Research Highlights
► Dark solitons repel each other for their coherent interaction.
► Dark solitons travel along different trajectories for the coherent interaction.
► Dark solitons attract each other for their incoherent interaction.
► Dark solitons both deflect along a parabolic trajectory for the incoherent case.
