摘要： An arrayed waveguide grating type optical multiplexer/demultiplexer including an arrayed waveguide grating having a plurality of channel waveguides. Concave end faces of input-side and output-side slab waveguides are connected to opposite ends of the diffraction grating. At least one input waveguide and at least one output waveguide are connected to the other concave end faces of the input-side and output-side slab waveguides, respectively. The focal length of the output-side slab waveguide end face is longer than the focal length of the input-side slab waveguide end face. The optical multiplexer/demultiplexer has a sufficiently flat wavelength-dependent spectrum response in passing channel spacings, and helps construct an optical wavelength multiple communication system having a good signal-to-noise ratio.

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.
