Abstract

We evaluate the effect of finite aperture gratings on the spectral and efficiency characteristics of guidedmode resonance filters. A simple analytical model based on the attenuation properties of the waveguide and a fixed length of the grating aperture is developed. The results from this model are in good agreement with experimental filters formed with subwavelength period photoresist gratings and solgel waveguides.
