Abstract:
1. An acousto-optic device, comprising: a core layer having a periodic photonic crystal structure in which unit cells of predetermined patterns are repeated; a first clad layer on a first surface of the core layer, the first clad layer having a refractive index that is different from a refractive index of the core layer; a second clad layer on a second surface of the core layer, the second surface being opposite the first surface, the second clad layer having a refractive index that is different from the refractive index of the core layer; and a sound wave generator configured to directly apply surface acoustic waves (SAW) to the core layer, the first clad layer, the second clad layer, or any combination thereof, wherein the core layer, the first clad layer, the second clad layer, or any combination thereof to which the SAW are applied includes an acousto-optic material.
