Guided-mode resonance refers to a sharp resonance effect in waveguide gratings where efficient energy exchange between reflected and transmitted waves occurs in a small parameter (wavelength, angle, or refractive index) range. High- efficiency optical reflection filters are obtainable using zero-order waveguide gratings based on this effect. In this paper, a new type of high-contrast (high efficiency and low- sideband) guided-mode resonance reflection filter is studied theoretically and experimentally. Low-reflection sidebands and symmetrical resonance lineshapes are achieved by incorporating thin-film Brewster effects for a TM-polarized incident wave. Experimental results verifying the feasibility of this concept are presented.
