Abstract: In order to obtain a reflection filter with peak wavelength of 1064 nm,guided-mode resonance effect was used. The spectra were calculated by using rigorous coupled wave method. First,a reflection guided mode resonance filter with peak wavelength at 1064 nm was designed by using a single layer structure.But the reflections in the range away from the peak wavelength were somewhat high due to the mismatch between the cover coating and substrate. By adding an antireflective layer,the reflections in the range away from the peak wavelength were reduced obviously. Then the grating thickness and grating period effects on optical properties were analyzed. The result showed that good optical properties could be obtained by the design.
