We propose to launch three-year comprehensive studies on the doped photopolymer materials for volume holographic recording, with their applications for optical information processing and storage. Based on current research results of developing the PQ/PMMA photopolymer, we will develop three novel photopolymer materials, including PQ doped co-polymer materials, Irgacure 784 PMMA photopolymer, and doped epoxy family polymer materials. The former two kinds of materials are expected to have better the recording dynamic range and sensitivity than PQ/PMMA photopolymer, as well as the third kind of materials is a new exploration for development novel materials. This research is divided into three phases. In the first year, we will focus on the fabrication of three materials and development of the physical mechanism of the holographic recording in our photopolymer materials. The results will provide the guidelines for designing and optimizing materials. During the same period, basic tools for measuring the optical and holographic properties of material will be constructed. In the second year, we will focus on experimentally characterizing the properties of volume holographic recording in our materials. The results can provide us to further optimize materials. In addition, according to holographic recording properties of the materials, we will explore their applications on optical information storage and processing. In the third year, based on the theoretical and experimental works, we shall continue the study on the volume holographic recording in these novel materials and explore the applications for optical information storage and processing. We plan to investigate three topics, including the planar integration of optical system using volume holograms, volume holographic multi-channel correlator, and fast parallel pattern recognition. In summary, this research will perform an intensive study on the material design, analysis, and applications on the doped photopolymer materials. These novel materials are expected to be a new invention, and the study will also possibly lead to exploring new physical mechanisms of holographic recording in photopolymer material.
