Abstract:

Coupling devices for SAWs, which permit switching of SAW power between channels. Channel waveguides are laid down on or in the surface of a substrate. The waveguides have a coupling region in which they are close to each other. The input waveguide is formed from a material whose acoustic wave velocity characteristic can be changed by an external means. Various means for altering the velocity of the SAW, such as electric or optical fields, are employed by applying them to the coupling region of the input waveguide.
