Abstract:	研究期間：10108~10207;According to the development in display and communication technology, the request for providing information for mobile devices has been highly demanded. Besides, digitalization of huge data accompanying with clouding computing make a storage scheme for nonvolatile memory, high storage capacity, high access rate and energy saving is needed. Holographic storage is one of few ways satisfying such demand, and then will be paid much attention. Besides, since volume holographic optical element can perform spatial and wavelength multiplexings, the technology will be utilized in photonic information processing and bio-medical imaging. However, volume holographic storage and element are both suffered from thermal expansion for breaking Bragg condition so that the function is destroyed. This proposal is for a three-year project, which is aimed to overcome the thermal expansion problem based on the technique we developed for collinear holographic system in the past years. In the first year, we will develop a temperature compensation model for volume holographic storage with low sensitivity in temperature variation. Thus, the diffraction efficiency will not change without changing the reading wavelength. In the second year, we will keep optimize the model and demonstrate the property with experiments. The target is to reach temperature compensation to a range of ±50℃. In the last year, we will study the application to volume holographic optical elements and biomedical imaging. Therefore, we can build up a new technology for volume holography without suffering from temperature variation.
