  • Method for compensating polarization mode dispersion, polarization mode dispersion compensator and optical fiber communication system
    Patent number: 6947194
    Abstract: An optical signal is introduced into a polarization rotator to control the optical signal so that the output of the optical signal is maximized through the rotation of a plane of polarization of the optical signal, and then, introduced into the polarizer to pass a linear polarization of the optical signal therethrough, and then, introduced into the optical electric power detector to detect the output of the optical signal.
    Type: Grant

    Date of Patent: September 20, 2005
    Assignee: Osaka University
    Inventors: Masayuki Matsumoto, Daniele Alzetta
