| 摘 要： | 给出求含有增益层与损耗层的突变与渐变折射率剖面多层平板波导导模的微扰与解析计算公式。举例讨论了导模模式的增益（或损耗）与结构参数和偏振的关系，本文方法较求解复本征值的打靶法等简便且节省机时，对于（半导体激光器与半导体激光放大器等）实际遇到的波导结构能给出精确数值结果，并可用以分析材料的增益系数或损耗对ＴＥ和ＴＭ模式及其增益的影响等问题。 |
| 关 键 词： | 光波导 复传播常数 增益 损耗 微扰 平板波导模 |

| Abstract: | The theoretical study on optical characteristics of multilayer optical waveguides with complex dielectric constants involves great quantities of computation to sovle the complex transcendental eigenvalue equation. In this paper an improved and generalized formula for calculating the complex modal refractive indeces of guided modes is presented. In combination with iteration method very exact results can be capidly obtained even for high loss or high gain structrues. The procedure is illustrated on 4 layer and 5 layer metal clad waveguides and the calculated results are compared with that obtained by other methods. |
