“…A second example of this effect is that nonlinear polarization rotation induced by wavelength division multiplexed interactions can lead to fast variations of the polarization states that impede the ability of standard PMD compensators to mitigate signal degradation that is due to PMD. This effect was observed by Khosravani et al [29] and by Lee et al [30]. It is my view that much work remains to be done to explore the interaction of nonlinearity and PMD and that it is a very interesting area for future research.…”

There has been a flood of recent work on polarization effects in optical fibers, most of it focused on polarization mode dispersion (PMD). There are good, practical reasons for this recent interest. As the data rate per channel increases, PMD becomes an increas-ingly important limitation in communication systems. However, my own interest in polarization issues was, at least originally, focused on more fundamental questions. Since nearly all the contributions in this volume focus on the more immediate practical issues that are a consequence of polarization effects, it seemed useful to me to focus this contribution on more fundamental issues. The nice thing about fundamental issues is that even though they attract less attention than immediate practical issues, they typically stay relevant longer and can impact practical issues 10-20 years in the future.Throughout the 1970s, a considerable body of work established the basic polarization properties of optical fibers. Much of this work was summarized by Kaminow in 1981 [1]. It was found that the birefringence ∆n/n is in the range 10 −4 -10 −9 , with communication fibers in the range 10 −6 -10 −7 . It was found that the intrinsic

“…However, OPMDCs cannot mitigate the rapid distorting effects of XPM which appear on the feedback control on the bit time scale of fractions of nanoseconds. As shown in some recent experiments [5], [7]- [9], when XPM-induced degradation is present, the efficiency of OPMDCs is drastically reduced. Moreover, with the aim of predicting such efficiency reduction, the study of depolarization due to the interaction of Kerr nonlinearity and PMD has been tackled in several experimental and theoretical works [10]- [12].…”

Abstract-A novel analytical model is proposed to predict the cross-phase modulation (XPM)-induced depolarization in a two-channel transmission system, in which the Stokes' vector of each channel rotates around a space-invariant pivot by a time-varying angle which depends on the total instantaneous optical power in the fiber, on the angle between pump and probe input Stokes' vectors, and on the walk-off between channels. The model leads to a simple formula of the probe degree of polarization (DOP) which is validated both by simulation and experiment. The model helps identify the key physical factors that determine the XPM-induced performance degradation of DOP-based first-order polarization-mode dispersion compensators, and experiments that quantify such degradation are presented.

“…Compensation of polarization mode dispersion (PMD) has been an important area of research in high-capacity optical communications for more than a decade [1,2]. While the vast majority of published work on PMD compensation (PMDC) has considered propagation in the optical fiber to be linear, it has been demonstrated that in some systems the impact of fiber nonlinearity must be taken into account [3][4][5][6][7][8]. Most of the work on PMDC in nonlinear systems has focused on the effects of cross-phase modulation (XPM) in wavelength-division-multiplexed systems.…”

“…Most of the work on PMDC in nonlinear systems has focused on the effects of cross-phase modulation (XPM) in wavelength-division-multiplexed systems. XPM can cause polarization fluctuations on the time scale of the bit period which can seriously degrade the performance of PMDC [4][5][6][7].…”

We simulate a 2000-km 10-Gb/s single-channel NRZ system with different polarization mode dispersion compensation (PMDC) techniques and compare the effectiveness of compensation with linear and nonlinear signal propagation. Significant differences are found between the results of PMDC with and without nonlinearity for all the compensation techniques that are examined. An analysis of PMDC based on linear propagation would not properly characterize PMDC in the nonlinear case. A three-stage compensator controlled by optimizing the signal eye opening is found to give large performance improvement with nonlinear propagation compared to single-stage PMDC.
