Study on wavelength-dependent diffraction Properties of Finite Size Volume Holographic Gratings

体全息光栅由于具有灵敏的布拉格角度和波长选择性等诸多优点，成为了全息、数据存储和多功能三维光学集成系统的首选研究对象。三维光学系统能够直接处理多维光学数据，具有光学并行传播和处理、光学的无干扰交叉传输、光束三维传播自由度以及空间和频率的多维复用等优点。如何充分发挥光学系统的优越性，制作小型化和全光化的光集成器件和系统，是目前国内外在光学信息处理和光通信领域中研究的一前沿课题。我们课题组一直从事衍射光学的性质、空间局域光折变体全启、记录和固定方法、局域体全息、三维光学系统微集成等方面的研究。本论文在课题组的前期工作中进一步研究和讨论了变波长读出局域体全息光栅的衍射特性，探索了局域体全息在集成光学器件方面的应用。Holographic gratings have become the preferred study hotpot in the fields of holographic data storage and multifunctional three dimensional optical system for its sensitive Bragg angular selectivity and wavelength selectivity et, al. 3D optical system have the function of the directly multi-dimensional data processing, and have -the many advantages such as optical parallel transmission and processing, non-cross interaction, optical transmission in 3D direction and space and frequency multiplexing. How to fully use its intrinsic virtues to develop a minimized and all-optical 3D optical system? It is thus an important direction of optical devices and their systems. In our research group, we devote ourselves to research the properties of diffraction optics, the recording and fixing technique of photorefractive local volume holograms, local photorefractive holograms and their 3D integration. In this dissertation, the diffraction properties of finite size volume holographic gratings reading by different readout beam and their applications in integrated optical devices are investigated
