摘要:
An acousto-optic device (10) having a wide range of diffraction angles and an optical scanner, a light modulator, and a display apparatus using the acousto-optic device are provided. The acousto-optic device (10) includes a core layer (11) having a periodic photonic crystal structure in which unit cells of predetermined patterns are repeated, a first clad layer (12) on a first surface of the core layer (11), the first clad layer (12) having a refractive index that is different from the refractive index of the core layer, a second clad layer (13) on a second surface of the core layer (11), the second surface being opposite the first surface, the second clad layer (13) having a refractive index that is different from the refractive index of the core layer, and a sound wave generator (14, 15, 16) configured to apply surface acoustic waves (SAW) to the core layer, the first clad layer, the second clad layer, or any combination thereof.
