摘要： A method of connecting waveguides and optical fibers includes the steps of forming the waveguides and a marker at the same time on a waveguide substrate when patterning the waveguides by a photolithography method, forming a clad layer on a region other than another region when the marker is formed so as to embed the waveguides, and forming a fitting pin groove at a position corresponding to a position of the marker. By using this fitting pin groove, a waveguide module and an optical fiber connector are connected so as to connect each of the waveguides and each of the optical fibers with each other. With this method, waveguides and optical fibers can be aligned and connected with each other easily and in a short period of time without employing an expensive aligning device.

Further, fiber guide grooves are formed in the fiber aligning jig, using the marker as a reference mark. The waveguide chip and the fiber aligning jig are abutted against each other, and the planar optical waveguide and the optical fiber are aligned with each other by means of a common guide pin laid along the corresponding pin guide grooves.

摘要： An optical line monitoring method and an apparatus for locating a failure point in an optical communication system, wherein a plurality of types of inspection light rays having wavelengths which are determined by cut-off wavelengths, which differ from each other, of short-wavelength pass filters installed at a plurality of branched ports of an optical coupler/splitter of the communication system are sent from a light source having variable wavelengths into one or more corresponding optical fiber lines of the system in sequence via an optical directional coupler and the optical coupler/splitter. Each time reflected light, corresponding to the inspection light, from one or more optical fiber lines is received, an output representing the intensity level of the reflected light is sent from a light receiver to an arithmetic circuit and stored in the arithmetic circuit. The arithmetic circuit calculates the reflected light intensity levels which correspond to the individual optical fiber lines according to the light receiver outputs which individually correspond to inspection light rays, whereby the position of the failure in the optical fiber line incurring the failure is identified.

摘要： A composite optical device has a first and second chips. The first chip has a substrate on which M pieces of optical waveguides for transmitting communication light, N pieces of optical waveguides for transmitting monitoring light and M-input/N-output star couplers are formed in an integrated form, and the second chip has a substrate on which N pieces of optical waveguides for transmitting communication light, N pieces of optical waveguides for transmitting monitoring light and N pieces of 2-input/2-output star couplers are formed in an integrated form. A first and second blocks holding optical fibers are joined respectively to the first and second chips. When the composite optical device in which the first and second blocks and the first and second chips are joined is incorporated into the optical communication system, a passive double star system is constructed. By using an MT connector instead of the first block and the first chip, a single star system can be rapidly constructed.

摘要： A 2-input/2-output directional coupler is arranged as an element coupler/splitter for a first stage, and 1-input/2-output coupler/splitters are used as element coupler/splitters for a second stage and subsequent stages. Output ports of these element coupler/splitters are concatenated with input ports of other element coupler/splitters to form a 2-input/multi-output coupler/splitter. An optical signal can be inputted through one input port of the first-stage 2-input/2-output directional coupler, and an optical signal for optical line monitoring can be inputted through the other input port. It is unnecessary, therefore, to use an optical wavelength division multiplexer/demultiplexer or other optical part which conventionally is connected at the time of optical line monitoring.

摘要： An optical waveguide component includes at least one main waveguide through which signal light and regenerating light propagate and a branch waveguide branching from the main waveguide, which are formed on the same substrate; a filter element disposed at a branch portion of these waveguides; and a plurality of reflecting elements having two reflecting faces, which are arranged in the extending direction of the branch waveguide. In the optical waveguide component, one reflecting face of the two reflecting faces is a face for reflecting the regenerating light to the filter element, and the other face is a face for reflecting the regenerating light to the direction deviating from the light axis direction of the branch waveguide, or the intervals between the reflecting elements are different from each other. This optical waveguide component enables the time-series signal processing of regenerating light to be performed accurately.

摘要： An optical coupler/splitter having an optical waveguide on the side of light incidence, two optical waveguides on the branched side, branched from the former optical waveguide and each having straight and curved sections, and a dielectric multi-layer film filter provided in a manner crossing the latter waveguides and common to them. The filter is so formed as to intersect with a straight section of one waveguide and with a curved section of the other, so that respective crossing angles between the filter and the branched optical waveguides differ from each other, thereby providing different reflection or transmission characteristics with respect to the branched optical waveguides. An optical signal having a variable wavelength and issued from a measuring apparatus based on the backscattering method is distinguished by the common filter of the coupler/splitter, making it possible to perform measurement of the losses of the branched optical waveguides independently without being affected by interference light. There is no need to provide a plurality of filters having different characteristics, and thus the coupler/splitter has a simplified structure and excellent productivity.

摘要： An optical waveguide component which has end faces to be connected with optical fiber connectors by means of guide pins, comprises an optical waveguide component body having an optical waveguide core portion, and a resin mold cladding portion covering all the faces of the optical waveguide component body except for the end faces of the optical waveguide component body. Each end face of the resin mold portion has guide pin holes which were formed with the optical waveguide core portion being used as a positioning reference. Since the guide pin holes for connection with the optical fiber connectors are formed in the resin mold portion which, preferably has some elasticity and which covers the optical waveguide component body, the guide pin holes and a substrate are not broken even if subjected to a load after connection.
