ACOUSTO-OPTIC DEVICE HAVING NANOSTRUCTURE, AND OPTICAL SCANNER, OPTICAL MODULATOR, AND DISPLAY APPARATUS USING THE ACOUSTO-OPTIC DEVICE

摘要

An acousto-optic device includes an optical waveguide in which incident light is able to propagate; a metal layer surrounding at least a first portion of the optical waveguide; a gain medium layer disposed in the first portion of the optical waveguide; and a sonic wave generator configured to generate surface acoustic waves (SAWs) and apply the SAWs to the optical waveguide and/or the metal layer.
