多个光伏空间亮孤子相互作用研究

用数值方法分析了多个平行传播一维光伏空间亮孤子之间的相干相互作用.结果表明，同相多个孤子相互作用时，它们不同于两个孤子时的周期性的融合和分开，而是会在整体吸引靠近过程中发生孤子的逐步融合作用.多个孤子相互之间发生能量耦合作用时，可简单归结为三种基本的相互作用模式.而邻近相互反相的多个孤子相互作用时，能保持很好的稳定传播特性，其对形成孤子阵列及阵列波导具有指导意义. 关键词： 光伏空间孤子 多个孤子 相互作用

Coherent collisions of multi photovoltaic bright spatial solitons

We present a numerical study of coherent collisions of multi photovoltaic bright spatial solitons. The result shows that when the colliding solitons are in-phas e, they will attract each other and the inner ones will fuse together gradually. When the relative initial phase between any two adjacent solitons is π2, they will experience a power transfer which includes three basic interaction modes. When the colliding solitons are out of phase, they will propagate stably, which may be useful for the formation of soliton arrays and waveguide arrays.
