摘要： An optical transmission/reception module in which an LD, a lens holder, which supports a lens, a partial wave filter, a lens holder, which supports a lens, and an optical fiber are all mounted to a housing block, coaxially along a first axis. A reflecting mirror, a lens holder, which supports a lens, and a PD are also mounted to the housing block, coaxially along a second axis which is parallel to the first axis. Cutouts are formed in the housing block for providing large openings forwardly of and perpendicular to a mounting surface for mounting the partial wave filter thereon and a mounting surface for mounting the reflecting mirror thereon. In such an optical transmission/reception module, it is possible to maintain the precision with which a partial wave filter, which passes a transmission light therethrough, and a reflecting member, which reflects a reception light, are mounted to a desired mounting angle at a high level, and to reduce assembly costs.

摘要： An optical coupler including optical fibers having gaps between first coverings and second coverings corresponding thereto. Each cladding of the two optical fibers is formed into a proper shape, with a taper of a proper thickness. The two optical fibers are then joined together, forming a joined portion which engages an engaging groove in a pair of blocks and the pair of blocks are affixed together by welding. Thereafter, the second coverings are affixed to cutouts in a retainer member. Lastly, the retainer, fitted to the blocks, is affixed thereto. Such an optical coupler is highly practical, does not allow deterioration of light dividing properties caused by changes in the length of the cladding joined portion as a result of an external stress, and prevents breakage of the joined portion.

摘要： In an optical transmitting and receiving module, a transmitting light beam having a wavelength &lgr;1 emitted from an light-emitting device passes through an optical demultiplexing filter and enters an optical fiber, and a receiving light beam emitted from an end face of the optical fiber is reflected from the optical demultiplexing filter and is incident on a light-receiving device. A cover for covering the front space of the optical demultiplexing filter is placed on a casing block, and a tongue piece serving as a returning-light preventing unit is formed on the cover. When a transmitting light beam emitted from the light-emitting device is reflected from the optical demultiplexing filter, the direction in which the reflected light advances is changed by the tongue piece so that the reflected light is not incident on the light-receiving device.
