A simplified method is presented for analyzing the optical characteristics of ridge MOS optical waveguides. Equations are derived for calculating the effective refractive indices and the absorption loss coefficients of the E(x)(pq) modes. The computations are performed for air-Au-air/SiO(2)/GaAs/AlGaAs ridge MOS waveguides. To achieve single-mode propagation with low absorption loss, appropriate selection of the structural parameters for this kind of waveguide is discussed.
提出了一种用于分析脊形MOS光波导光学特性的简化方法。推导了用于计算E(x)(pq)模的有效折射率和吸收损耗系数的方程。针对空气-Au-空气/SiO(2)/GaAs/AlGaAs脊形MOS波导进行了计算。为了实现低吸收损耗的单模传播，讨论了这种波导结构参数的适当选择。
