  • Patent number: 8824895
    Abstract: An object of the present invention is to provide a radio-on-fiber unit and a radio-on-fiber system which can transmit/receive signals at adequate rates especially, to/from a mobile device. A first aspect of the present invention relates to a radio-on-fiber unit (3) which includes an antenna array (1) and a light modulator array (2). The light modulator array (2) comprises antenna elements (5) and light modulators (7) that are connected with the respective antenna elements via electric circuits. The optical waveguide (13) is composed of linear optical waveguides (13) that are arranged along the light modulators (7) included in certain lines among the light modulators (7). The light modulator array (2) comprises reflection units (17) for connecting two adjacent linear optical waveguides with each other. Consequently, a signal light inputted to a light input unit (11) is outputted from a light output unit (15) via each linear optical waveguide (13).

  • Patent number: 8693005
    Abstract: Problems To provide a method for evaluating characteristics of MZ interferometers in an optical modulator having a plurality of MZ interferometers. Means for Solving Problems When an optical modulator includes a plurality of MZ interferometers, the 0-degree component contains a signal derived from an MZ interferometer other than the MZ interferometers for evaluating the characteristic. For this, it is impossible to accurately evaluate the characteristic of the MZ interferometers. The present invention does not use the 0-degree component normally having the highest intensity. That is, the characteristic of the MZ interferometers are evaluated by using a side band intensity of the component other than the 0-degree component.

  • Patent number: 8366251
    Abstract: According to one aspect of the invention, a remanufacturing method of a liquid container forms an inlet in a certain area, for example, a buffer chamber, other than a specific section including liquid reservoirs and flow paths adjoining to and directly communicating with a bubble trap flow path in the liquid container. In the state of closing a liquid feeder and opening an air open structure, the remanufacturing method injects a liquid through the inlet to fill a space in the upstream of the inlet with the liquid. In the state of opening the liquid feeder and closing the air open structure, the remanufacturing method injects the liquid through the inlet to fill a space in the downstream of the inlet with the liquid. The remanufacturing process seals the inlet after completion of the injection of the liquid. This arrangement enables the liquid to be refilled into the liquid container without damaging the functions of the liquid container.
