摘　　要：通过对四方、立方晶系的纵向电光效应和多维正常声光效应的研究 ,选定了四方晶系的KDP晶体和立方晶系的GaP晶体作为多维正常声电光器件的最佳晶体 ,并通过计算两种晶体的声光互作用性能参量 ,确定了它们的二维、三维、四维正常声电光效应的最佳工作模式。研究结果为多维正常声电光器件的设计与制作打下了良好基础。多维声电光器件在多路光通信和多通道光信息处理中有应用前景。The longitudinal electro-optic effect and the multi-dimensional isotropic acousto-optic effect in square system and cubic system are researched. KDP of the square system and GaP of the cubic system are determined as optimum crystals for multi-dimensional isotropic acousto-electro-optic devices. Through calculating the function characters of acousto-optic interaction in the two crystals, some optimum operating modes for its two-dimensional, three-dimensional and four-dimensional isotropic acousto-electro-optic effect are determined. Multidimensional acousto-electro-optic devices have applications in multi-channel optic communication and optic signal processing.
