  • Dispersion compensation with low polarization mode dispersion
    Patent number: 5974206
    Abstract: A dispersion compensator exhibiting low polarisation mode dispersion is constructed from a polarisation beam-splitter, a .pi./4 rotation Faraday rotator, and a matched pair of polarisation maintaining fibres provided with a matched pair of chirped Bragg reflection gratings. The waveguides are oriented with respect to the beam-splitter so that light reaching the waveguides from the beam-splitter via the rotator is launched into both waveguides with a polarisation state aligned with the same polarisation axis (i.e. both fast or both slow).
