RT Book, Section T1 On some physical properties of a new photopolymerisable glass with high refractive index species for holographic data storage A1 Martínez Matos, Óscar A1 Cheben, Pavel A1 Calvo Padilla, María Luisa A1 Rodrigo Martín-Romo, José Augusto A1 Monte Muñoz de la Peña, Francisco del AB We report recent results obtained with volume holographic gratings recorded in a new photopolymerisable glass modified with high refractive index species at molecular level. Various not previously observed performances have been achieved for diffraction efficiency and angular selectivity. In particular, new overmodulation effects have been obsreved for the first time experimentally in an amorphous material.
