摘要： A first polarization controller controls a polarization state of measured light. A second polarization controller controls a polarization state of an optical sampling pulse. The measured light and the optical sampling pulse having the polarization states controlled are input to an optical fiber. An optical signal output from the optical fiber is transmitted to a polarizer. A first control unit adjusts the first polarization controller based on the measured light output from the optical fiber and the measured light output from the polarizer. A second control unit adjusts the second polarization controller based on an optical sampling pulse output from the optical fiber. Waveform measurement is performed by using the output of the polarizer.

摘要： In a method and an optical switch by which a signal light is accurately switched even if a polarization state of a signal light inputted has a fluctuation, power of an output light of a polarizer which receives a signal light extracted from an output light of a nonlinear optical medium is monitored and a polarization state of an input signal light to the nonlinear optical medium is controlled so that the power becomes minimum (or maximum). The polarization state of the input signal light is monitored, a calculation of performing a predetermined conversion is executed to the polarization state of the input signal light, and a calculated polarization state is recorded (or recorded without conversion). A polarization state of a control light with respect to the input signal light is monitored and the polarization state of the control light is controlled so as to coincide with the polarization state of the input signal light recorded.

摘要： A method and a display for elevator allocation evaluating are provided. When an elevator allocated to a hall call is selected by employing two different view points such as a real and a future call evaluation index, an elevator allocation reason and a balance between the two view points can be easily grasped. An elevator allocated to a hall call is evaluated on orthogonal coordinates in which the real call evaluation index and the future call evaluation index are defined as an X and a Y coordinate axis. Evaluation indexes of first to fourth elevator cars are evaluated by employing contour lines of a synthetic evaluation function, which is represented as the real and the future call evaluation index. A weight for allocating is displayed visually.

摘要： Reflection means such as a mirror are provided on the output end of an optical fiber, and the input signal light and control light are returned to the optical fiber. Although the zero-dispersion wavelength of the optical fiber fluctuates in the longitudinal direction, if the length is relatively short, it is possible to manufacture a high yield of optical fibers, which monotonically changes the zero-dispersion wavelength. Therefore, a relatively short optical fiber with a monotonic zero-dispersion change can be used. Since the zero-dispersion change is monotonic and the optical fiber is short, the amount of change in the zero-dispersion wavelength is small and the bandwidth becomes broader when the control light is set at the position of the average zero-dispersion wavelength. Additionally, although the length of the optical fiber is short, the operating length is twice as long and thus the generation efficiency does not degrade.
