| Outline of Final Research Achievements |
Holographic data storage has been expected to be a next-generation optical data storage system because of its large storage capacity and fast transfer rate. In this study, We focused on AlN crystal as a new holographic recording material and investigated holographic recording properties in the deep UV spectral region. We found that AlN crystals shows larger refractive index grating than the other semiconductors. We also investigate the properties of light-induced absorption and reveal the recording model of AlN crystal.
