ABSTRACT:
Method and apparatus is described for interacting bulk acoustic waves with an optical waveguide on a common substrate to switch, modulate or deflect guided light at a very high speed. A direct application lies in a monolithic optical analog-to-digital converter. To this effect, a plurality of transducer elements regularly spaced in an array across the optical waveguide are controlled with constant or variable phase shift along a slope, thus causing deflection of the guided light in a fashion analog to phased-array radar technique. A fully integrated monolithic device is constructed combining the bulk acoustic wave generating and optical waveguide functions.
