摘要： An apparatus and method for underwater coupling of a fiber-optic cable to a light source without exposing the light source to the surrounding water. The apparatus employs an optically clear coupling element having one or more blind holes on one surface sized to snugly hold a fiber optic cable. The coupling element closes a watertight enclosure containing a light source such that the blind holes are on the exterior of the enclosure. Light emitted by the light source can pass through the optically clear coupling element to be received by fiber-optic cables fitted into the exterior blind holes. The fiber optic cables can be removed and replaced without opening the enclosure and exposing the light source to contact by the surrounding water.

摘要： Transmitter module for optical interconnections, comprising a metal container housing an optical emitting device, an integrated circuit containing the driving circuit of the emitting device and an optical fibre extending outside the container, the emitting device being mounted on a metallic ground area realized on the integrated circuit. The cathode is electrically connected to the ground area and the anode is connected to a second metal area, connected with the output of the driving circuit. The module uses a type of assembly which minimises problems due to the length of the connecting wires, to parasitic effects and to the effects of signal reflections due to impedance mismatching. It also requires reduced power for its operation and it is provided with a structure facilitating dissipation.

摘要： An optical circuit element has a beam splitter which is formed with a plurality of grooves in optical waveguides, or formed in such a manner that the central axes of the waveguides to be coupled are set off from one another or the shape of the waveguides is modified. Further, an integrated type optical circuit device include: an optical circuit element having a plurality of optical waveguides on the input side and having a beam splitter which is formed with a plurality of grooves in the optical waveguides to split the light guided through the optical waveguides: and plural kinds of input light generating sources each arranged corresponding to one of the optical waveguides on the input side.
