Abstract: Provided is an acousto-optic device including an elastic medium; a meta structure formed on a first surface of the elastic medium, and an elastic-wave generating unit which generates an elastic wave in the elastic medium. The meta structure includes a first layer and a second layer that is formed on the first layer. The at least one of the first layer and the second layer includes a predetermined repetitive pattern.

Abstract: Provided are an acousto-optic element, an acousto-optic element array, and a display apparatus including the acousto-optic element array. The acousto-optic element includes: an acousto-optic modulator which includes an acousto-optic layer formed of an acousto-optic material; a light supplier which supplies light to the acousto-optic modulator in a first direction; a first sound-wave modulator which applies first elastic waves to the acousto-optic modulator in a second direction; and a second sound-wave modulator which applies second elastic waves to the acousto-optic modulator in a third direction. The light supplied from the light supplier to the acousto-optic modulator is deflected by diffraction caused by the first elastic waves applied from the first sound-wave modulator and diffraction caused by the second elastic waves applied from the second sound-wave modulator, and is output from the acousto-optic modulator through a front side of the acousto-optic modulator.
