Abstract
An acousto-optic structure according to an exemplary embodiment of the present invention is a stacked structure for inducing an interaction between incident acoustic wave and incident optical wave, and it includes: a pair of multi-layered structures including a structure in which two layers with different acoustic impedance and optical impedance are alternately arranged in a direction in which the acoustic wave and the optical wave propagate; and a cavity layer disposed between the pair of multi-layered structures in the direction in which the acoustic wave and the optical wave propagate, and made of a medium having acoustic impedance and optical impedance that are different from those of interfacing layers at both sides, wherein the two layers are symmetrically arranged with respect to the cavity layer so that the acoustic wave and the optical wave may be confined in the cavity layer.
