    摘要: A polarization controller includes a phase retarder having a rotation about an {1,0,0} axis that receives an optical signal from a waveguide structure. At least one nanoelectromechanical dielectric perturber produces ±45° birefringent axes by placing the at least one nanoelectromechanical dielectric perturber at selective positions around the phase retarder to produce dynamic change in the effective index in one of the modes existent in an extraordinary axial direction.

    摘要: A PMD device includes a first stage that receives a signal and performs rotation about {1,0,0} on the signal. The first stage outputs a first signal. A second stage receives the first signal and performs a rotation about {0,0,1 } on the first signal. The second stage outputs a second signal that represents the alignment the PMD of various frequencies into a common direction. A third stage receives the second signal and provides the necessary frequency dependent variable in the {1,0,0} direction to cancel the PMD in any specified frequency range.

    摘要: A polarization mode dispersion (PMD) feedforward compensator compensates first and second order PMD. An optical signal is provided to a PMD detector that senses first and second order PMD in the optical signal and produces control signals for the PMD compensator. The PMD compensator comprises, in series, a first polarization controller, an adjustable delay, a second polarization controller, a first fixed delay, a third polarization controller and a second fixed delay.

    摘要: In optical media (e.g., an optical fiber) having first and second order polarization mode dispersion, the relationship between the polarization mode dispersion and the change in the measured averaged state of polarization of an optical signal in the media as a function of the signal's bandwidth can be predictable. Accordingly, first and second order polarization can be determined by measuring a series of the averaged state of polarization's for an optical signal with varying signal bandwidths.
