A well-developed technology of depositing ZnO piezoelectric transducers on crystals for bulk-wave acoustic delay devices has been applied to the manufacture of microwave acousto-optic devices. Narrowband acousto-optic units operating at frequencies as low as 250 MHz and as high as 10 GHz have been built. Broadband (1 GHz bandwidth) units have been built with center frequencies ranging from 2.5 GHz to 6.5 GHz. Transducer technology is described, along with characteristics of acousto-optic components built using the deposited transducer technology.
