| 摘 要： | 从理论上研究具有复折射率的多层光波导的关键是求解复数超越本征方程，计算工作量是庞大的，本文提出了改善计算这种光波导中导模折射率的普遍公式。将它与叠代法结合起来，即使对于高损耗或高增益的结构，也能迅速地求得很精确的结果。文中以四层和五层的金属覆盖层波导作为实例说明这一计算方法，并将计算结果与其它方法所得的结果进行了比较。 |

| 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 |
| Keywords: | KTP ion exchanged waveguide optical damage lattic constant. |
