Abstract
An optical deflecting device of optical waveguide type comprising: a conductive or semi-conductive monocrystalline substrate, or a monocrystalline substrate having a conductive or semi-conductive, epitaxial or oriented film provided on the surface thereof; an optical waveguide comprising an epitaxial or oriented ferroelectric film provided on the surface of the monocrystalline substrate; and an upper electrode disposed on top of the optical waveguide. In the optical deflecting device, the conductive or semi-conductive monocrystalline substrate, or the conductive or semi-conductive, epitaxial or oriented film provided on the monocrystalline substrate acts as a lower electrode. The laser beam introduced into the optical waveguide is deflected by applying a voltage between the upper electrode and the lower electrode.
