Abstract
Guided mode resonant filters (GMRFs) are potentially useful as wavelength selective devices for DWDM telecom and sensor applications. These elements consist ofa high frequency grating deposited on an optical waveguide. In this presentation we investigate several approaches to modeling the characteristics of finite aperture GMRFs. Experimental GMRFs were fabricated with photoresist gratings with different grating characteristics and apertures were deposited on planar waveguides with specific refractive indices and thickness in sol-gel materials. Good agreement between our model prediction and experimental data for the reflection efficiency and spectral bandwidth were found. Limiting the aperture of GMRF below a few millimeters reduces the diffraction efficiency and increases the spectral bandwidth.
