从理论上预测并通过实验验证了一种新型滤光片。该滤波器在薄膜波导光栅的导模谐振条件下工作。在传统上禁止 TM 反射的布鲁斯特角处会产生高效反射滤波器响应。获得与谐振峰附近的布鲁斯特效应引起的谐振峰相邻的低反射率边带。对于 1064 nm 波长的 TM 偏振高斯激光束，双层波导光栅在薄膜布儒斯特角处产生 94% 的实验反射率。 (C) 1998 年美国光学学会。
A new type of optical filter is predicted theoretically and verified experimentally. The filter operates under guided-mode resonance conditions in a thin-film waveguide grating. A high-efficiency reflection filter response is produced at the Brewster angle at which TM reflection is classically prohibited. Low-reflectance sidebands are obtained that are adjacent to the resonance peak induced by the Brewster effect in the neighborhood of the resonance peak. A double-layer waveguide grating yields 94% experimental reflectance at the thin-film Brewster angle for a Gaussian laser beam with TM polarization at the 1064-nm wavelength.
