摘要： In the dispersion-compensating system of the present invention, a demultiplexer demultiplexes optical signals in a signal wavelength band of 1520 nm to 1620 nm propagating through a first common transmission line into C band (1520 nm to 1565 nm) and L band (1565 nm to 1620 nm). Then, the demultiplexer outputs the optical signals of C band into a first branched transmission line and the optical signals of L band into a second branched transmission line. A first dispersion-compensating device is provided on the first common transmission line and compensates for the dispersion in C and L bands. A second dispersion-compensating device is provided on the second branched transmission line and compensates for the dispersion in L band, which has not fully been compensated for by the first dispersion-compensating device. Hence, the dispersion of optical transmission line can fully be reduced in a wide signal light wavelength band.

摘要： The present invention relates to a light source apparatus having a structure for stably supplying broadband pulsed light having a wavelength spectrum with an excellent flatness over a wide band. The light source apparatus employs, as a seed light source, a short-pulsed light source having such an excellent output pulse characteristic that the frequency bandwidth extending until the output pulse drops by 10 dB or 20 dB from a peak is 5 THz or more. The light source apparatus also includes a broadband light producing fiber having an optical characteristic suitable for combining with the short-pulsed light source. The broadband light producing fiber inputs pulsed light from the pulsed light source, and produces the broadband pulsed light by utilizing a nonlinear optical phenomenon. This structure yields broadband pulsed light having such a wavelength spectrum that a region whose power fluctuation is suppressed to 6 dB or less extends over 100 nm or more.

摘要： There are provided a rare-earth permanent magnet and a manufacturing method thereof capable of simplifying manufacturing process and improving productivity through advanced ability to produce net shapes. In the method, magnet material is milled into magnet powder, and the magnet powder and a binder are mixed to prepare a mixture. Next, the prepared mixture is formed into a green sheet. Thereafter, the green sheet is held for predetermined time at binder decomposition temperature in non-oxidizing atmosphere, whereby depolymerization reaction or the like changes the binder into monomer and thus removes the binder. The green sheet with the binder removed therefrom undergoes pressure sintering such as SPS method so as to obtain a rare-earth permanent magnet 1.
