RT Journal Article T1 Photopolymerizable glasses incorporating high refractive index species and ionic liquid: A comparative study A1 Villafranca Velasco, Aitor A1 Hernández Garay, María de la Paz A1 Calvo Padilla, María Luisa A1 Cheben, Pavel A1 Monte Muñoz de la Peña, Francisco del AB Three different holographic photomaterials belonging to the class of photopolymerizable glasses have been synthesized using sol-gel techniques, and characterized with the purpose of a comparative study. Their behavior is analyzed in terms of achieved refractive index modulation, dark diffusion mechanism, diffraction efficiency and optical quality; in order to determine their suitability for different holographic applications.
