摘要： A method of connecting optical fibers with each other or with optical waveguides using a connection aid. The connecting aid has a hole into which the fiber is inserted and secured and from which hole a tip portion of the fiber protrudes slightly, and an adhesive or solder is applied to a gap between two adjacent connection aids or between an end surface of the waveguide and an opposed surface of the connection aid. The connection aid may contain an array of two or more optical fibers. The connection method can be used to produce reliable, strong and low-loss connections between the optical fibers or between and optical waveguide and the optical fibers.

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.
