The analytical result of the tir mirror shows that this type of awg device with tir mirrors has high fabrication tolerance . the tapered waveguide and the output waveguide of the device are designed and improved . simulation results indicate that introduction of tapered waveguides with different widths and design improvement of the output waveguide can both improve the performance of the awg device 对全内反射镜的分析表明这种全内反射型的awg器件具有较高的制作容差；改进设计了awg器件中的楔形波导和输出波导，模拟结果表明不等宽楔形波导的引入可以改善awg器件的性能，对输出波导进行改进设计同样可以提高awg器件的性能。
