对三层介质光栅的零级衍射效率进行了理论和实验研究。观察到由于导波的激发而引起的尖锐的共振异常，这显著增加了系统的反射率。作为一个可调谐的窄带波长滤波器的反射制度的结构的操作被证明。
The zeroeth order diffraction efficiency of a three-layer dielectric grating is studied theoretically and experimentally. A sharp resonance anomaly due to the excitation of guided waves is observed, which increases significantly the reflectance of the system. The operation of the structure as a tunable narrow-band wavelength filter in a reflection regime is demonstrated.
