    摘要: An optical switch comprising: an electrode-optic crystal substrate (1, 1'); a central waveguide (21); a pair of input waveguides (22, 23), and a pair of output waveguides (24, 25). A refractive-index-changed region (R') is provided symmetrically within some part of the central waveguide. Switching from the straight-through state to the branching state or vice versa is carried out by introducing a change in the refractive index of the index-changed region.

    摘要: A compact optical device operating as a WDM (wavelength division multiplexing) filter is provided. The optical device includes a slab optical waveguide having first and second end faces opposed to each other, a plurality of first optical waveguides connected to the first end face of the slab optical waveguide, and a plurality of second optical waveguides connected to the second end face of the slab optical waveguide. Each of the second optical waveguides includes a first cavity connected to the slab optical waveguide and a second cavity acutely connected through a first reflecting surface to the first cavity. The second cavity is terminated by a second reflecting surface. Each second cavity is so configured as to be folded back to the corresponding first cavity, so that the optical device can be made compact in setting a required optical path difference between the second optical waveguides. This optical device can be used as an optical multiplexer or an optical demultiplexer in a system adopting WDM.
