ABSTRACT:
A waveguide-type light deflector or modulator includes an optical waveguide for guiding a light beam therethrough along a light path, and an interdigital transducer for generating surface elastic waves in the optical waveguide to diffract the light beam and for propagating the surface elastic waves in opposite directions across the light path, the interdigital transducer being transversely disposed to the light path in a substantially central position in the light path. In the light deflector, an alternating voltage with a continuously varying frequency is applied to the interdigital transducer to enable the surface elastic waves to continuously diffract and deflect the light beam. In the light modulator, the application of an alternating voltage to the interdigital transducer is controlled to vary the diffraction efficiency of the light beam, thereby to modulate the light beam.
