| Summary: | 碩士 === 國立交通大學 === 電子物理系所 === 94 === Holographic data storage using photorefractive crystals as storage materials is a potential technology. How to obtain long time data storage is a primary issue. Using tow-center recording in photorefractive crystals is one solution. This thesis is based on Kukhtarev equations. We use a single-carrier band-transport model with two energy levels and obtain both analytical and numerical solutions. With these solutions we obtain space charge field term and are able to simulate the recording and fixing processes. We select two crystals, LiNbO3 and Bi12SiO20, and use their parameters for simulation respectively. We then discuss how material parameters affect the recording and fixing processes in this thesis.
