为了研究扩散效应对相干屏蔽光伏孤子对相互作用的影响.将两个平行传播相干屏蔽光伏孤子光束作为入射波,采用数值方法求解有扩散效应的波传播方程.结果表明,在扩散效应影响下,两相干屏蔽光伏孤子光束同相相互作用不是原来融合,而是使它们趋于分离,且光束之间存在能量的耦合;异相孤子的相互作用不再是简单的相互排斥,在一定的条件下,两束孤子光束既互相排斥,又同时向同侧偏转.

The purpose of this research is to study the influence of diffusion on the interaction between coherently screening-photovoltaic spatial soliton pairs. Taking the two coherent screening-photovohaic spatial soliton beams with the same polarization and wavelength as the input wave, we numerically solve the beam propagation equation in the absence of diffusion. The result shows that the in-phase interaction will result in the separation of the two solitons from each other, accompanied by the energy coupling between the beams, which is different from the case without diffusion field. And for the case of the anti-phase interaction, the two solitons are no longer simply separated. Under certain conditions, they are exclusive to each other but deflect simultaneously to the same side.
