A design approach to guided-mode resonance filter containing an absentee layer with an antireflective surface is presented. This design approach is reliable for the design and analysis of guided-mode resonance filter containing an absentee layer with an antireflective surface at an arbitrary incidence. The antireflection condition of guided-mode resonance filter containing an absentee layer is obtained. For the absentee layer with a fixed optical thickness, the resonance wavelength can be selected, with the low-sideband features and the filter linewidth kept almost the same by using different materials. In addition, the resonance wavelength and its linewidth can be tuned almost linearly in a broad spectral band as the incident angle is varied due to high angular tolerance of the antireflection features of the filter in the range of small angle.
