Rigorous coupled-wave analysis (also called the Fourier-modal method) is an efficient tool for the numerical analysis of grating diffraction problems. We show that, with only a few modifications, this method can be used efficiently for the numerical analysis of aperiodic diffraction problems, including photonic crystal waveguides, Bragg mirrors, and grating couplers. We thus extend the domain of applications of grating theories.
严格耦合波分析（也称为傅里叶模态法）是用于光栅衍射问题数值分析的有效工具。我们表明，只需进行一些修改，该方法就能有效地用于非周期衍射问题的数值分析，包括光子晶体波导、布拉格反射镜和光栅耦合器。因此，我们扩展了光栅理论的应用领域。
