金属覆盖渐变折射率光波导在截止点附近传播特性的近似分析

Optical Characteristics of Metal-clad Graded-index Waveguides in Near Cutoff: Approximate Analytical Approach

本文提出一种分析金属覆盖渐变折射率光波导在截止点附近的光学特性微扰近似方法,并仔细地讨论了金属覆盖指数折射宰光波导在截止点附近的传播特性和截止条件。

An approximate analytical approach, which is used to analyze the optical characteristics of metal-clad graded-index waveguides in near cutoff, is presented in this paper. The mode propagation characteristics and cutoff conditions of inetal-clad exponential index wavguide are discussed in detail.
