Abstract
Photopolymers are suitable for recording thick phase holograms. In addition, photopolymers are stable media with high diffraction efficiency; therefore, they are widely used as holographic recording media. A photopolymer must satisfy certain criteria to qualify as a practical recording medium. However, the reaction processes of such photopolymers are highly complicated. In this study, we have simulated the formation of diffraction gratings in photopolymers using the diffusion model based on elementary reactions, and analyzed their diffraction characteristics in detail by the beam propagation method. Moreover, we also performed experimental interference fringe recording and evaluated the recording characteristics of photopolymer media. In addition, we propose a simulation method for the signal evaluation. This simulation method can replicate three dimensional writing/readout processes of hologram. We consider that the results of our analysis will provide useful information for the development of holographic data storage.
