| 摘 要： | 利用变分法和数值模拟的方法研究了克尔型自聚焦介质平板波导中正交极化、中心重合的双光束的传输规律，得到了两光束做类孤子的“互陷”传输的条件，分析了在平板波导的线性双折射为零以及不能忽略的两种情况下“互陷”传输的特点.结果发现“互陷”传输的光束与严格意义的矢量空间孤子之间存在本质的不同.

| Abstract: | The propagation of two orthogonally polarized coaxial light beams in plannar waveguides is studied by variational approach as well as numerical method. The condition for soliton-like mutually-trapped propagation of the two beams is obtained. We analysed the different characteristics of mutually-trapped propagation in two cases with or without linear birefringence. We find that there is an essential difference between mutually-trapping beams and the rigorous vector spatial soliton. |
