Abstract: PROBLEM TO BE SOLVED: To provide an all-optical means applicable to re-shaping of pulse by selecting an optically nonlinear material and periodic variations, so that a re-shaped optical output pulse becomes an optical output pulse substantially limited in conversion. SOLUTION: A WDM (a system having one or more operating wavelengths) signal from a transmitter 11 is propagated downstream to an amplifier 15, and demultiplexed by a conventional demultiplexer 17. Next, the demultiplexed channels are supplied to each BSPR(Bragg soliton pulse re-shapers) 161-169. Each BSPR is adjusted to a proper wavelength. Next, the reshaped pulses are multiplexed by a conventional multiplexer 18 and propagated downstream to a using means. The BSPR to be used consists of a Bragg diffraction grating formed in a waveguide showing nonlinearity with respect to the electric field of the pulse propagated via the BSPR. Furthermore, the BSPR is selected so that the nonlinearity of the waveguide substantially averages the dispersion, a fixed distorted pulse is substantially limited in conversion.

Abstract: PROBLEM TO BE SOLVED: To provide a Raman light amplifier based on a shorter amplifier fiber and lower pumping power. SOLUTION: The light amplifier 10 is provided with a chalcogenide glass optical waveguide 14 having optical input and output ports connected with the chalcogenide glass optical waveguide 14, a pumping optical waveguide, and wavelength-adjustable pumped laser 12. The pumping optical waveguide connects the wavelength-adjustable pumped laser 12 to the chalcogenide glass optical waveguide 14.

Abstract: In an optical fiber communication system a pulse reshaper can transform a distorted input light pulse into a reshaped output light pulse. The disclosed pulse reshaper is an all-optical pulse reshaper that comprises an optical waveguide having an effective length, the waveguide connecting the input and the output and comprising optical non-linear material, with a periodic variation of an effective refractive index of the optical waveguide. The optically non-liner material and the periodic variation are selected such that the reshaped output light pulse is a substantially transform-limited output light pulse.
