提出一种实现亮-暗复色光伏孤子的方法.不共轴的两束同频率相干但反相的亮光束共同形成一中空光束,在此暗区引入另一束不同频率的亮光束.这三束光在一定条件下可以通过非线性相互作用而形成亮-暗复色孤子.通过数值分析的方法对这种亮-暗复色光伏孤子的空间动力过程进行了研究.研究表明,这种亮-暗结构具有光控光特性.

We present a scheme to realize coupled dark-bright photovoltaic spatial-soliton pairs with two-wavelength components. With the propagating beam method we numeri cally study the spatial dynamic properties of these coupled solitons, finding th e possibility to use such coupled solitons in all-optical beam switching.-
