Abstract: Couplers are disclosed for use with guided elastic waves and guided optical waves. The coupling is effected by means of a coupling region having a different phase velocity characteristic than that of the waveguide. The presence of the coupling region causes the waves traveling in the waveguide to become highly leaky. These leaky waves then encounter a second waveguide or transducer and are coupled into it. Utilizing the electroacoustic effect in the acoustic wave devices and the electrooptic effect in the optical wave devices, the phase velocity characteristic of the coupling region is controllable, permitting switchable couplers.
