本文提出了一种分析和设计反射式阵列波导光栅的模型。该器件由常规AWG的一半组成，阵列中的每个臂波导端接移相器和Sagnac环形反射器。通过单独调整每个臂中的移相器和Sagnac反射率，获得了文献中先前报道的附加功能，因为这使得能够定制AWG的光谱响应。报道了绝缘体上硅工艺中高斯型通带形状器件的设计和实验验证。方法来获得平坦和任意的光谱响应的描述和支持的仿真结果。
In this paper, a model for the analysis and design of a reflective Arrayed Waveguide Grating is presented. The device consists of one half of a regular AWG where each arm waveguide in the array is terminated with a phase shifter and a Sagnac loop reflector. By individually adjusting the phase shifter and Sagnac reflectivity in each arm, additional functionality to that previously reported in the literature is attained, since this enables tailoring the spectral response of the AWG. The design and experimental demonstration of Gaussian pass-band shape devices in Silicon-on-Insulator technology are reported. Methods to obtain flattened and arbitrary spectral responses are described and supported by simulation results.
