通过调用慢波近似,波动方程恢复了菲涅耳方程的形式。以前开发的用于近轴光束传播的代码可以扩展到模拟任何角度的反向反射和衍射。给出了平面波导光栅和斜角弯曲的结果
By invoking the slow-wave approximation, the wave equation resumes the form of the Fresnel equation. Codes developed previously for the paraxial beam propagation can be extended to simulate the backward reflection and diffraction at any angle. Results of planar waveguide gratings and a beveled corner bend are presented.<<ETX>>
