三层非线性平面光波导TM波的精确色散关系

Exact dispersion relation for TM waves guided by nonlinear three-layer planar waveguide

对于介质薄膜波导的一边或两边复盖有介电常数与光强成正比的非线性介质的三种不同结构,本文导出了三层非线性平面光波导TM波的精确色散关系.对称三层非线性平面光波导的数值计算实例与有限元法的结果完全一致.

Exact dispersion relations for TM waves guided by thin dielectric films covered on one or two sides media of intensity-dependent refractive indexes have been derived. Numerical results for symmetric structure are in good agreement with that obtained by the finite element method.
