摘要
本文用数值方法计算了由线性和非线性介质构成的三层平板结构波导中TE模的色散关系及模的演变。针对自聚焦和自散焦介质分别进行了讨论,获得了具有潜在应用价值的结论。
Numerical calculation of TEm mode dispersion relation and evolution in three-layered slab waveguide is presented. A linear dielectric layer is bounded by two nonlinear dielectric layers. The discussion is focused on both self-focusing and self-defocusing medium. Some results with potential applications are given.
