摘要： In an optical switch, a carrier-accumulating layer in which injected carriers are accumulated is provided on a semiconductor substrate having a waveguide formed thereon so that injected effective carriers tend to be accumulated in an effective part, and the burden on a driving circuit is thus reduced to realize high-speed operation. At the same time, when a clad on the carrier injection side, of clad layers formed on both sides of the waveguide, is a second clad layer, and a clad on the substrate side is a first clad layer, a third clad layer is formed on the first clad layer to reduce propagation loss in the waveguide.

摘要： An optical path control device includes a hole formed perpendicularly to the plane of a substrate, an optical waveguide formed on the substrate to cover the hole, an upper electrode formed on the optical waveguide above the hole, a lower electrode formed on a bottom part of the hole, and a voltage application unit for applying a voltage between the upper and lower electrodes. As the applied voltage is controlled to change an electrostatic attraction force between the upper and lower electrodes and the magnitude of flexure of the waveguide is thus changed, the traveling direction of light can be changed into an arbitrary direction.

Also an integrated circuit of an advanced function-integrated type is provided, comprising an interference system such as a Mach-Zehnder interferometer wherein weighting of the Mach-Zehnder interferometer is constituted for image processing and signal code conversion.
