Abstract
The present invention uses a single substrate to provide a small-size optical waveguide element that requires no optical axis adjustments, can be driven at a low voltage, is excellent in light utilization efficiency, and can rapidly two-dimensionally deflect a light beam. A right-triangle upper electrode and a rectangular transparent upper electrode are formed on top of a thin-film optical waveguide formed on a conductive substrate to serve as a lower electrode, and an emission right-angled prism is secured on top of the transparent upper electrode. A voltage is applied between the upper electrode and the conductive substrate, and between the transparent upper electrode and the conductive substrate. A horizontal deflection is performed upon application of a voltage to the upper electrode and a vertical deflection is performed upon application of a voltage to the transparent upper electrode.
