Abstract
The present disclosure provides an acousto-optic device comprising an acousto-optic layer, an electromagnetic radiation source, and an acoustic source. In an embodiment, the acousto-optic layer has a substantially planar shape defining an x-y plane and functions as an optical waveguide to optical waves and as an acoustic waveguide to acoustic waves propagating in the x-y plane. In an embodiment, the electromagnetic radiation source is optically coupled to the acousto-optic layer and configured to deliver electromagnetic radiation therein. In an embodiment, the acoustic source is acoustically coupled to the acousto-optic layer and configured to deliver acoustic energy therein and is configured to adjust a wavelength of the acoustic energy. In an embodiment, the electromagnetic radiation source and the acoustic energy source are positioned to provide an intersection between the electromagnetic radiation and the acoustic energy, which at least partially scatters light from the intersection out of the x-y plane.
