摘要： An controllable optical device for integrated optics applications comprises a material structure, at least one optical cavity defined in said material structure and having a refractive index, a dimension, and first and second sides, said material structure including a plurality of alternating transparent layer regions of alternating refractive indices forming first and second Bragg mirrors disposed one at each of said first and second sides of said optical cavity, and at least one transducer provided on said material structure for the generation of acoustic waves adapted to modulate said refractive index and said dimension of said optical cavity whereby to influence a light beam incident on said Bragg mirrors and said optical cavity. The device can be designed to have acoustic and optic waves propagating in arbitrary directions.
