| 摘 要： | 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.

| Abstract: | 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-photovoltaic 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 betwe... |
