Abstract
An acoustooptic transducer includes a base and cap which may be mated axially along a certain length of an optical fiber. The base and cap each include a semicircular channel fabricated along one axis. A zinc oxide layer is sandwiched between two metal layers in each of the semicircular channels. When the cap and base are mated, each of the semicircular channels of metal and zinc oxide correspond to form coaxial cylindrical channels of zinc oxide sandwiched by layers of metal surrounding the fiber. Under an applied electrical force, to electrodes of the metal layers, the zinc oxide produces focused acoustic waves for coupling to the light transmitted through the optical fiber. In another embodiment of this invention, the layer of zinc oxide sandwiched between the metal layers may be applied directly to a predetermined length of the optical fiber.
