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： A Raman amplifier applicable to a wavelength division multiplexing optical transmission system is proposed. The Raman amplifier, which can make good use of a wavelength range, comprises an optical fiber for Raman amplification and a pump light introducing means. The zero-dispersion wavelength of the optical fiber and the wavelength of the pump light are nearly equal. The wavelength of pump light is preferably in the range where the absolute magnitude of the chromatic dispersion of the optical fiber is less than 0.3 ps.nm−1.km−1. A range near a zero-dispersion wavelength cannot be utilized as a signal range because waveform deterioration of signal light occurs due to four wave mixing. This range can be utilized effectively as a wavelength range of exciting light for Raman amplification.

摘要： High peak pulse light is incident on an optical fiber having a dispersion decreasing region which serves as a main region for generating supercontinuum or idler light and in which the chromatic dispersion does not increase but at least partially decreases in the direction in which light travels. The fiber can be applied to broad band width idler light generation with both light transmission directions. Four wave mixing upon incidence of the light on the dispersion decreasing region of the optical fiber are efficiently obtained.

摘要： There are provided a rare-earth permanent magnet and a manufacturing method thereof capable of preventing deterioration of magnet properties. In the method, magnet material is milled into magnet powder. Next, a mixture is prepared by mixing the magnet powder and a binder made of long-chain hydrocarbon and/or of a polymer or a copolymer consisting of monomers having no oxygen atoms. Next, the mixture is formed into a sheet-like shape so as to obtain a green sheet. After that, the green sheet is held for a predetermined length of time at binder decomposition temperature in a non-oxidizing atmosphere so as to remove the binder by causing depolymerization reaction or the like to the binder, which turns into monomer. The green sheet from which the binder has been removed is sintered by raising temperature up to sintering temperature. Thereby a permanent magnet 1 is obtained.

摘要： The present invention relates to an optical measurement apparatus and wideband light source apparatus equipped with a structure for making it possible in optical measurement utilizing light in a near-infrared region to expand the measurement range to the longer wavelength side in the near-infrared region. The optical measurement apparatus comprises a wideband light source apparatus for outputting irradiation light to irradiate an object to be measured, and a detector for detecting the light arriving from the object irradiated with the irradiation light. The wideband light source apparatus comprises a light source section, and an optical fiber for expanding the spectrum width in an intensity spectrum of seed light from the light source section. In particular, the wideband light source apparatus outputs light having an intensity spectrum with an expanded spectrum width within the optical fiber as irradiation light so as to maintain such a spectrum intensity as to compensate for the decrease in light-receiving sensitivity of the detector in a wavelength region in at least a part of a sensitivity-decreasing region of 2 μm to 3 μm where the light-receiving sensitivity of the detector decreases in the near-infrared region.
