  • Waveguide amplifier and pumping scheme for a waveguide amplifier
    Publication number: 20020131161
    Abstract: The invention is related to a waveguide amplifier with an input for optical signals and an output for optical signals with at least one piece of amplifying waveguide with at least one mean for coupling pump laser modules to the amplifying waveguide which contains Tm ions. The invention is also related to a pumping scheme for waveguide amplifier feeding two different wavelengths in to the waveguide.

  • System for and a method of compensating polarization dispersion in an optical transmission system
    Patent number: 6317240
    Abstract: To increase the bit rate and distance of transmission of data by optical fiber, the system compensates polarization dispersion of the link by means of a polarization controller, a differential delay generator for generating a differential delay between two orthogonal polarization modes and a control unit for the polarization controller. It further includes a chromatic dispersion compensator inserted in the link and which applies a fixed value of compensation which minimizes the error rate of the signals received after transmission. Application to long-haul optical transmission via standard fibers.
