摘要： The invention provides an optical switch including a substrate which has conductivity or semiconductivity, an optical waveguide layer which is formed on the substrate, and a control electrode which is formed on the optical waveguide layer. The optical waveguide layer includes an incident-side channel waveguide to which a light signal is incident and plural outgoing-side channel waveguides branched from the incident-side channel waveguide. The control electrode forms a reflection plane reflecting the incident light signal near a crossover portion of the plural outgoing-side channel waveguides by applying voltage to the optical waveguide layer with the substrate to control a refractive index of the optical waveguide layer, and switches propagation paths of the light signal.

摘要： A ridge type channel optical waveguide is formed in an optical waveguide layer. A cladding layer having a refractive index smaller than that of the optical waveguide layer and having a width substantially the same as that of the channel optical waveguide and having a thickness which increases in a tapered manner toward an end surface, is formed above both of a light entering end portion and a light exiting end portion of the channel optical waveguide. By the cladding layer, a mode field diameter in a direction orthogonal to a substrate surface can be enlarged, and a coupling loss with an optical fiber can be greatly reduced. Further, loss due to mode mismatching can be prevented by a light confining effect.

摘要： 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.
