Photopolymer Materials for Holographic Data Storage Applications

摘要

Photopolymer materials are practical materials for use as holographic recording media, as they are inexpensive and self-processing. By understanding the mechanisms present during recording in these materials their limitations for certain processes can be improved and a more efficient, environmentally stable material can be produced In this paper we briefly review the application of photopolymer materials in the area of holographic data storage. In particular we discuss the recent development of the Non-local Polymerisation Driven Diffusion Model, (NPDD) including absorption and inhibition, and analysis of the photochemical effects present during the evolution of holographic grating formation. The inclusion of these effects allows a more accurate understanding of the photo-polymerisation process.
