应用一种简化的方法对五层MOS光波导的光学特性进行了分析,给出了TE模传播常数和吸收损耗系数的近似计算公式,并结合计算结果检验了本方法及公式的精度,为实现波导中TE_0模低损耗单模传输,讨论了某些波导参量的选择.
The optical properties of the five-layer MOS optical waveguide are analyzed by a simplified method. The approximate formulas for the propagation constants and absorption loss coefficients of the TE mode are given. The accuracy of the proposed method and the formulas are tested in combination with the calculated results. Waveguide TE_0 mode low loss single mode transmission, the choice of some waveguide parameters are discussed.
