Abstract
In this paper we show the analysis and experimental results of using a volume holographic grating to increase the wavelength bandwidth over which light is coupled into a thin-film optical waveguide. Partial matching of the dispersion relationships of a hologram fabricated in dichromated gelatin with a waveguide/grating coupler etched in glass, show an increase in the full-width half-maximum wavelength (FWHM) bandwidth from approximately 0.25 nm to greater than 5 nm.
