Abstract
An acousto-optic device employing strong interband coupling in a multi-mode, spiral-shaped optomechanical waveguide is disclosed. The acousto-optic device includes multiple interdigitated transducers to produce phonons, which are directed to the optomechanical waveguide at an angle. By confining the produced phonons to the optomechanical waveguide, using phonon confining elements and/or a suspended structure, the interband coupling is increased. Through the use of spatial mode multiplexers at either end of the optomechanical waveguide to block or pass different spatial optical modes, one can create an acousto-optic modulator or an optical isolator.
