A guided-mode resonant filter (GMRF) based on the structure of anti-reflection (ar) thin filmwaveguide is proposed to realize three-primary-color filter with narrow-band.
为获得性能优良的三基色窄带滤光片，提出了一种基于减反射薄膜波导光栅结构的导模共振滤光片。

The Fourier spectral analysis method is applied to the input-output coupling problem of a prism-thin filmwaveguide system. The input-output coupling equations are solved fast and exactly.
