On some physical properties of a new photopolymerisable glass with high refractive index species for holographic data storage

Abstract

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.
