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.
