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