| 摘 要： | 讨论了高斯型空间光孤子在光折变介质光学晶格的传输行为,运用分步傅里叶变换法对传输方程进行数值分析.研究表明:单个斜入射高斯型光孤子在周期性光学晶格中会局限于入射波导传输或在合适振幅的情况下穿过若干波导再自陷于某个波导;而当同时存在正入射和斜入射孤子时,两者相遇后会发生反射或透射,并可通过斜入射光孤子的振幅选择反射或透射.

| Abstract: | The transmission behavior of Gausian-type spatial optical soliton in optical lattices made by photorefractive media is investigated through the numerical analysis on the transmission equation. The method of splitstep Furier transformation is used in the analysis. When a Gausian-type soliton is input in an oblique orientation, it will trapped in the incident lattice or travel through some lattices and then self-trapped in one, which is determined by the amplitude of the soliton. If a straight and an inclined Gausian-type solitons are input at the same time but different position, they will encounter each other, and then the latter reflect or transmit determined by its amplitude. |
