摘要： A receiving device is provided capable of avoiding reception of unnecessary energy when a signal waveform actually changes on a receiving side. An impedance control circuit includes a sensing unit to sense one or more of a voltage, current, or power of a signal to be received by a receiving circuit. The impedance control unit varies an input impedance according to the change in the sensed one or more quantities so that the received signal will be reflected. Thus the excess energy of the signal is reflected and fed to any other receiving circuit achieving stable communications.

摘要： A transmission apparatus for differential communication includes a driver bridge circuit and a pair of noise protection circuits. The driver bridge circuit includes four output devices that are independently connected between each of a pair of transmission lines and a power line or a ground line. Each noise protection circuit is provided to a corresponding transmission lines. Each noise protection circuit includes a ground potential detector and an impedance controller. The ground potential detector detects a potential of the corresponding transmission line with respect to the ground line. The impedance controller causes an impedance of the corresponding transmission line with respect to the ground line to become equal to an impedance of the other transmission line with respect to the ground line, when the detected potential becomes outside a predetermined potential range.

摘要： An optical waveguide type optical terminator forms an optical waveguide structure including at least an optical absorption core (103) which is formed on a clad layer (102) and includes a portion composed of silicon in which an impurity of 1019 cm−3 or more is doped, and is used by being optically connected in series with an optical waveguide including a core (105) composed of silicon. The optical absorption core (103) is sufficient provided that, at least, an impurity of around 1019 cm−3 is doped therein. For example, its impurity concentration is sufficient provided that it falls within a range of 1019-1020 cm−3. The existence of this impurity causes absorption of light in the optical absorption core (103).

摘要： A high-order mode filter includes a slab region, a band-shaped projection elongated in an optical waveguide direction, a first optical waveguide including a disturbance element and a second optical waveguide. The disturbance element is formed by doping impurities into the slab region, thus indicating a lower refractive index than the slab region. Both the first optical waveguide and the second optical waveguide are alternately arranged. The first optical waveguide may include a disturbance element positioned close to the projection, while the second optical waveguide may include a disturbance element distanced from the projection in the slab region. The high-order mode filter causes a large high-order mode loss due to interference between a removable high-order mode and an intentional high-order mode at the connecting face between the first optical waveguide and the second optical waveguide, thus reducing reflected light and stray light.
