  • Abstract
    An electrooptic Bragg-deflection modulator using a corrugated waveguide is discussed. A coupling between transmitted and diffracted waves caused by a Bragg diffraction grating is controlled by an incident angle change. By combining a grating and a prism deflector, a large angle deflection is performed with a low driving voltage. Numerical examples are presented for LiNbO3waveguides, and are compared with those of the modulator where the coupling is controlled by an index change.
