摘要：A prism pair (103p) is employed as an optical deflecting element (103a). Theprism pair (103p) is constructed by a slab waveguide (103b), and first and second upperelectrodes (103c,103d) and first and second lower electrodes (103e,103f) arranged onand under the slab waveguide. These electrodes are shaped into a wedge shape (e.g.,triangular shape), and change the refractive index of a part of the slab waveguide (103b)by utilizing the electrooptic effect to change the propagation direction of light. Asubstrate comprises an integrated waveguide (211). A dielectric multi-layered film mirror(212) is arranged at the bending portion of the optical waveguide (211) to have an angleof 45 degree to the center line of the optical waveguide. The mirror (212) is formed byproviding a plurality of mutually-parallel slits (205) in a part of the optical waveguide.
