离散谱折射率法优化设计深刻蚀、单模GaAs/GaAlAs脊形光波导

A more detailed analysis of deep-etched,single-mode GaAs/GaAlAs multiple-layer optical rib waveguides is presented using the discrete spectral index method (DSIM).The fabrication tolerance of the obtained low-loss,single-mode optical rib waveguides with a large mode size is analysed as well.The result indicates that single-mode rib waveguides obtained by this method have large fabrication tolerance.
