  • Interaction of nonlinearity and polarization Mode Dispersion
    Journal of Optical and Fiber Communications Reports, 2004
    Co-Authors: Curtis R. Menyuk
    Abstract:

    The derivation of the coupled nonlinear Schrödinger equation and the Manakov-PMD equation is reviewed. It is shown that the usual scalar nonlinear Schrödinger equation can be derived from the Manakov-PMD equation when polarization Mode Dispersion is negligible and the signal is initially in a single polarization state as a function of time. Applications of the Manakov-PMD equation to studies of the interaction of the Kerr nonlinearity with polarization Mode Dispersion are then discussed.

  • Electrical estimation of polarization Mode Dispersion parameters for compensation
    Journal of Lightwave Technology, 2003
    Co-Authors: W. Xi, Tulay Adali, A.o. Lima, Wei Wang, John Zweck, Curtis R. Menyuk
    Abstract:

    A method to estimate the parameters of polarization Mode Dispersion (PMD) from the received signal power is developed and used to mitigate pulse distortion due to PMD.

  • importance sampling for polarization Mode Dispersion
    IEEE Photonics Technology Letters, 2002
    Co-Authors: Gino Biondini, William L Kath, Curtis R. Menyuk
    Abstract:

    We describe the application of importance sampling to Monte-Carlo simulations of polarization-Mode Dispersion (PMD) in optical fibers. The method allows rare differential group delay (DGD) events to be simulated much more efficiently than with standard Monte-Carlo methods and, thus, it can be used to assess PMD-induced system outage probabilities at realistic bit-error rates. We demonstrate the technique by accurately calculating the tails of the DGD probability distribution with a relatively small number of Monte-Carlo trials.

  • comparison of polarization Mode Dispersion emulators
    Journal of Lightwave Technology, 2001
    Co-Authors: I T Lima, Curtis R. Menyuk, R Khosravani, P Ebrahimi, E Ibragimov, Alan E Willner
    Abstract:

    We analyze polarization Mode Dispersion (PMD) emulators comprised of a small number of sections of polarization-maintaining fibers with polarization scattering at the beginning of each section. Unlike previously studied devices, these emulators allow the emulation of a whole ensemble of fibers. We derive an analytical expressions and determine two main criteria that characterize the quality of PMD emulation. The experimental results are in good agreement with the theoretical predictions.

  • Introduction to polarization Mode Dispersion in optical systems
    Journal of Optical and Fiber Communications Reports, 2004
    Co-Authors: L.e. Nelson, R.m. Jopson
    Abstract:

    This introduction covers concepts important to the understanding of polarization Mode Dispersion (PMD), including optical birefringence, Mode coupling in long optical fibers, the Principal States Model, and the time and frequency domain behavior of PMD. Other topics addressed include the concatenation rules, bandwidth of the Principal States, PMD statistics and scaling, PMD system impairments, and PMD outage probability calculations.

  • polarization Mode Dispersion
    Optical Fiber Telecommunications IV-B (Fourth Edition), 2002
    Co-Authors: H. Kogelnik, R.m. Jopson, L.e. Nelson
    Abstract:

    Publisher Summary Polarization Mode Dispersion (PMD) is a linear effect that can be compensated in principle. In an ideal circularly symmetric fiber, the two orthogonally polarized Modes have the same group delay. However, in reality, fibers exhibit a certain amount of birefringence because of imperfections in the manufacturing process or mechanical stress on the fiber after manufacture. It is noted that fluctuations in the polarization Mode and fiber birefringence produced by the environment lead to Dispersion that varies statistically with time and frequency. PMD causes different delays for different polarizations and when the difference in the delays approaches a significant fraction of the bit period, it leads to pulse distortion and system penalties. Environmental changes— including temperature and stress—cause the fiber PMD to vary stochastically in time. PMD, illustrating the basic concepts, the measurement techniques, the PMD measurement, the PMD statistics for first- and higher orders, the PMD simulation and emulation, the system impairments, and the mitigation methods has been summarized in the chapter. Both the optical and the electrical PMD compensations are considered.

  • jones matrix for second order polarization Mode Dispersion
    Optics Letters, 2000
    Co-Authors: H. Kogelnik, L.e. Nelson, J P Gordon, R.m. Jopson
    Abstract:

    A Jones matrix is constructed for a fiber that exhibits first- and second-order polarization Mode Dispersion (PMD). It permits the Modeling of pulse transmission for fibers whose PMD vectors have been measured or whose statistics have been determined by established PMD theory. The central portion of our Model is a correction to the Bruyere Model.

  • Polarization Mode Dispersion beyond first order

    Abstract:

    The phenomena associated with second and higher order polarization-Mode Dispersion are of interest to designers of high-speed lightwave systems. We describe measurement techniques, theoretical statistical predictions, simulations, and experiments investigating this realm of polarization-Mode Dispersion.
