Paper Abstract

Photopolymer materials are practical materials for use as holographic recording media due to the fact that they are inexpensive, self-processing materials with the ability to record low loss, highly diffraction efficient volume holographic gratings. Extensive studies have been carried out on the behaviour of the various chemical components in such materials, with photosensitizers in particular receiving much attention, as they are an important component in initialising the photopolymerisation reaction. However in all such analyses dye diffusion is neglected. To further develop such materials, a deeper understanding of behaviours the photosensitizer present during the formation of holographic gratings in these materials has become ever more crucial. We report on experimental results and theoretical analysis of the diffusion rate of Erythrosine B, in a Polyvinylalcohol/Acrylamide layer.
