Abstract :
Electrical characteristics of a new type of acoustic transducer have been investigated theoretically and experimentally. The agreement between calculated and measured results is excellent. The transducer consists of an acoustic superlattice, made of periodically poled LiNbO/sub 3/ (PPLN), with acoustically matched boundaries, facilitating the construction of acousto-optic (AO) devices through monolithic integration.
