TLDR
In this paper, the Manakov-PMD equation was derived using multiple-length-scale techniques and it was shown that the scalar nonlinear Schro/spl uml/dinger equation is valid when the signal is initially in a single polarization state.Abstract:
Aspects of the interaction of the Kerr nonlinearity and polarization mode dispersion (PMD) are reviewed. The basic equation that governs this interaction on the length scale of interest in optical fiber communications systems is the Manakov-PMD equation. This equation is derived using multiple-length-scale techniques. The focus of the derivation is the elucidation of common misunderstandings and pitfalls rather than mathematical rigor. It is shown that the scalar nonlinear Schro/spl uml/dinger equation is valid when PMD is absent and the signal is initially in a single polarization state. Two examples are then presented that illustrate the complexity of the interaction between nonlinearity and PMD. The first example considers the interaction of a nonlinearly induced chirp with PMD. As the power increases, one can obtain an improved eye opening relative to the case when PMD is absent. The second example considers the effect of nonlinear polarization rotation in a wavelength-division-multiplexed system. When nonlinear polarization rotation is important, the principal states of polarization become time dependent and PMD compensation becomes ineffective. This problem can be mitigated through the use of line codes.read more

Regular and Chaotic Dynamics
TL;DR: In this article, a self consistent treatment of the subject at the graduate level and as a reference for scientists already working in the field is presented. But the focus is on the mechanics for generating chaotic motion, methods of calculating the transitions from regular to chaotic motion and the dynamical and statistical properties of the dynamics when it is chaotic.

Analytical Fiber-Optic Channel Model in the Presence of Cross-Phase Modulation
TL;DR: In this article, a simple but accurate analytical model for the fiber-optic channel affected by cross-phase modulation (XPM) is proposed and validated through numerical simulations, which describes XPM as a time-varying and frequency-selective complex fading, whose impact and statistical properties can be analyzed.

Stability of solitons in birefringent optical fibers. I: Equal propagation amplitudes
TL;DR: It is shown that while linear birefringence will lead to a substantial splitting of the two polarizations over 20 km, this effect can be eliminated by use of the Kerr nonlinearity.

Stability of solitons in birefringent optical fibers. II. Arbitrary amplitudes
TL;DR: In this article, the propagation of short pulses in birefringent single-mode fibers is considered, and it is shown that above a certain amplitude threshold, whose size increases with bireringence, the two partial pulses lock together and travel as one unit.

Pulse propagation in an elliptically birefringent Kerr medium
TL;DR: In this paper, the coupled nonlinear Schrodinger equation for optical propagation in a birefringent Kerr medium was derived with particular emphasis on optical fibers and it was shown that shadows form when two pulses of opposite polarization interact, i.e., the emerging pulses no longer have their original polarizations.

Polarization-Mode Dispersion
TL;DR: In this article, it is shown that fluctuations in the polarization mode and fiber birefringence produced by the environment lead to dispersion that varies statistically with time and frequency.

Intensity discrimination of optical pulses with birefringent fibers.
TL;DR: An intensity discriminator for optical pulses can be made with a birefringent fiber using an intensity-dependent state of polarization out of the fiber for separating the intense subpicosecond pulses from the weaker uncompressed background.
