Interaction of nonlinearity and Polarization Mode Dispersion
Journal of Optical and Fiber Communications Reports, 2004Co-Authors: Curtis R. MenyukAbstract: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.

importance sampling for Polarization Mode Dispersion
IEEE Photonics Technology Letters, 2002Co-Authors: Gino Biondini, William L Kath, Curtis R. MenyukAbstract: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.

Three Representations of Polarization Mode Dispersion
Journal of Optical and Fiber Communications Reports, 2004Co-Authors: Hermann A. Haus, P. B. PhuaAbstract:Polarization Mode Dispersion (PMD) can be described in Jones space, Stokes space, or energy space. The three representations are compared and it is shown that equivalent information required for the prediction of the transmission eye-diagram is contained in the Jones space and energy space descriptions. Isotropic Dispersion is suppressed in the Stokes space formulation.

Manakov solitons and Polarization Mode Dispersion
Chaos, 2000Co-Authors: Y. Chen, Hermann A. HausAbstract:The effect of Polarization Mode Dispersion (PMD) on Manakov solitons and Dispersion managed solitons is treated analytically and by numerical simulation. In the analytic approach the internal motion of the Manakov soliton is represented as a damped harmonic oscillator. The PMD functions as a white noise source driving the oscillations. It is shown that the solitons can withstand PMD up to a certain instability threshold for which an analytic expression is obtained. This threshold is also evaluated for Dispersion managed solitons.

Optics Letters, 2000Co-Authors: Y. Chen, Hermann A. HausAbstract:Analytical expressions are presented for Manakov solitons perturbed by Polarization Mode Dispersion (PMD). Comparison is made with computer simulations. Dispersion-managed solitons are also studied. It is concluded that at high bit rates solitons are superior to linear return-to-zero propagation with regard to PMD.

Group velocity, energy, and Polarization Mode Dispersion
Journal of The Optical Society of America B-optical Physics, 1999Co-Authors: Hermann A. HausAbstract:The group-velocity concept of a complex of Modes is investigated, and the findings are related to power and energy. A special case of interest is Polarization Mode Dispersion. This approach permits a generalization of Polarization Mode Dispersion to the case of Polarization mixing of multiple Modes. Further, it is shown that first- and second-order Polarization Mode Dispersions are related to an energy matrix.

A Theory of Polarization-Mode Dispersion of Spun Fibers
Journal of Lightwave Technology, 2009Co-Authors: Antonio MecozziAbstract:We give a compact theory of the Polarization-Mode Dispersion (PMD) in spun fiber. For periodically spun fibers, the theory shows that the asymptotic behavior of the PMD can be predicted by a simple procedure from the two-dimensional Fourier transform of the birefringence correlation function.

Statistics of the Polarization Mode Dispersion dynamics.
Optics Letters, 2007Co-Authors: Antonio Mecozzi, Cristian Antonelli, Misha BrodskyAbstract:We characterize the joint two-time statistics of the Polarization-Mode Dispersion (PMD) vector. Good agreement with experimental PMD measurements taken on an installed system is achieved. The results can be used to obtain the temporal evolution of the average penalty of a system close to an outage condition.

Introduction to Polarization Mode Dispersion in optical systems
Journal of Optical and Fiber Communications Reports, 2004Co-Authors: L.e. Nelson, Robert Meachem JopsonAbstract: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.

Polarization Mode Dispersion
Optical Fiber Telecommunications IV-B (Fourth Edition), 2002Co-Authors: Herwig Kogelnik, Robert Meachem Jopson, L.e. NelsonAbstract: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.

Optics Letters, 2000Co-Authors: Herwig Kogelnik, J P Gordon, L.e.

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.

Solutions to the dynamical equation of Polarization-Mode Dispersion and Polarization-dependent losses
Journal of The Optical Society of America B-optical Physics, 2000Co-Authors: Yi Li, Amnon YarivAbstract:We study the evolution of optical signals in single-Mode optical fibers in the presence of Polarization-Mode Dispersion and Polarization-dependent losses. Two geometric vectors on the Poincare sphere are defined to characterize the effects of Polarization-Mode Dispersion and Polarization-dependent losses on the optical field in the fiber. By solving the dynamical equation for these two vectors, several general statistical results are obtained. The practically important weak Polarization-dependent-loss situation is discussed in detail.

Measurement of high-order Polarization Mode Dispersion
IEEE Photonics Technology Letters, 2000Co-Authors: Avishay Eyal, P.-o. Hedekvist, Amnon YarivAbstract:We demonstrate a new method to measure high-order Polarization Mode Dispersion (PMD) using the Jones matrix exponential expansion. High-order PMD is characterized by measuring a series of characteristic matrices, which are convenient quantities for analyzing PMD effects in the time-domain. An experimental method is developed to estimate the validity range of the exponential expansion.
