摘要： It is an object of the present invention to reduce the size of a circuit and the adverse effects of fabrication errors, while increasing yield. Signal light incident on a circuit through input waveguides propagates from the exterior to interior of the circuit while rotating counterclockwise. The signal light passes through a point of inflection in the center of the circuit, subsequently propagate clockwise from the interior to exterior of the circuit, and then exit output waveguides. Two arms constituting a delay circuit and optical couplers can be integrated together at such an interval that they are not coupled together. Therefore, the size of the circuit can be reduced compared to the prior art.

摘要： A product code block generated by adding an outer code block and an inner code block to digital information signal arranged in matrix is received at least twice by a code error correction apparatus. In decoding the first received product code block by use of an inner code parity, an error flag is set for an inner code block having an uncorrectable error by an inner code parity. In decoding the second received product code block by use of an inner code parity, the error flag is referenced so that an inner code block that could be correctly decoded or corrected in the second decoding of all the inner code blocks having an uncorrectable error in the first decoding is replaced by the second inner code block. Also, the check information such as a check sum is generated and stored each time of receiving, and an error flag is set for even an inner code block that could be corrected in either the first or second decoding, if the check sums for them fail to coincide with each other.

摘要： A method for adjusting a characteristic of a guided-wave optical circuit which includes one or more waveguides formed by a substrate, a cladding layer formed on the substrate, and a core portion having one or more cores embedded in the cladding layer. The method is carried out by producing a reversible thermal hysteresis phenomenon, after the clading layer and core portion have been formed. The thermal hysteresis phenomenon is produced in a thermal hysteresis produced region preselected so as to include at least a portion of the cladding layer and/or the core portion, thereby adjusting a refractive index difference between the cladding layer and the core portion. To produce a reversible thermal hysteresis phenomenon, the following steps are carried out: raising the temperature of the thermal hysteresis produced region to a predetermined temperature; maintaining the predetermined temperature of the thermal hysteresis produced region for a predetermined time period; and cooling the thermal hysteresis produced region at a predetermined cooling rate. At least one of the values of the predetermined temperature, predetermined time period, and predetermined cooling rate is controlled so that the refractive index difference between the cladding layer and the core portion is adjusted to a desired value, thereby adjusting the characteristic of the guided-wave optical circuit.

摘要： An apparatus has a parameter initial value calculator, a force reference impression part, an evaluation data measurement part, an allowable value setting part, a viscosity parameter calculator, an end determining part, and an inertia parameter adjusting part. The force reference impression part intermittently supplies a force reference to an impedance controller. The evaluation data measurement part measures setting time of time response, an overshoot amount, and the number of vibration times. The allowable value setting part sets allowable values of the overshoot amount and the setting time. The viscosity parameter calculator calculates a viscosity parameter with which the setting time becomes shortest. The end determining part determines the end or continuation of the process by comparing the adjustment values with the allowable values. The inertia parameter calculator adjusts the inertia parameter according to the adjustment values of the overshoot amount and the setting time.

摘要： The present invention relates to an automatic dispersion compensating optical link system. Carrier suppressed RZ encoded optical signals generated using carrier suppressing means and binary NRZ code or partial response code, or carrier suppressed clock signals generated using carrier suppressing means and clock signals are transmitted on an optical transmission line. Two bands of the carrier suppressed RZ encoded optical signals or carrier suppressed clock signals transmitted on the optical transmission line are each divided into bands and are received. Phase information of the respective basebands is extracted from the binary NRZ code components or partial response code components or clock signals in each band and the relative phase difference thereof is detected. The chromatic dispersion value of the optical transmission line is then calculated from the relative phase difference.
