摘要
本文应用有效折射率/有限元法(EI-FEM),计算和分析了半导体(量子阱)脊形光波导的模式特性、模式场分布及其变化规律.检验了EI-FEM的精度,分析了其产生误差的原因.扩展了EI-FEM,将其用于求解耦合波导系统,确定了方向耦合器的耦合特性及其变化规律.
Abstract The effective index-finite element method (ELFEM) is employed to calculate and analyze the mode characteristics and field distributions for rib waveguides. The accuracy of the new approximate method is assessed by comparing with other accurate and approximate methods. Then,the EI-FEM is further developed to calculate the coupling characteristics of rib waveguide directional couplers.PACC: 0260, 4280L
