Polarization mode dispersion in short fiber lengths

Journal of the Optical Society of America A, 2006
We perform Monte Carlo simulations of the statistical properties of the differential group delay for fiber lengths less than and of the order of the birefringence correlation length. We find that the manner in which quantities related to the polarization mode dispersion evolve along the fiber depends significantly on the model assumed for the form of ...

Characterization of the time dependence of polarization mode dispersion

Optics Letters, 2004
We elaborate on a recently proposed model of the temporal dependence of polarization mode dispersion in long fiber links. We evaluate the probability that a channel of a wavelength-division multiplexed system never incurs an outage, and the range of frequency over which the parameters that characterize the temporal statistics of the differential group ...

Mitigation of polarization mode dispersion

1999 IEEE LEOS Annual Meeting Conference Proceedings. LEOS'99. 12th Annual Meeting. IEEE Lasers and Electro-Optics Society 1999 Annual Meeting (Cat. No.99CH37009), 2003
There is a need for PMD mitigation. The increasing demand for bandwidth is driving most telecommunication operators toward the deployment of large capacity transmission systems. For distances of 300km or longer, 20% of the installed fiber plant is not suitable for 10 Gb/s transmission, and 75% is not suitable for 40 Gb/s.

On-line simultaneous monitoring of polarization mode dispersion and chromatic dispersion

Applied Optics, 2006
We have developed new expressions for power fading and average power fading owing to polarization mode dispersion (PMD) and chromatic dispersion in terms of the angle of precession of the output state of polarization about the PMD vector. Based on these expressions, a simple and novel pilot-tone-based technique for simultaneous monitoring of chromatic ...

Polarization-mode dispersion cancellation using periodic polarization modulation

SPIE Proceedings, 2003
In this paper we present a novel approach allowing cancellation of polarization mode dispersion (PMD) using a technique involving periodic polarization modulation, passing the optical signal through a polarizer and then sampling it. Digital post processing following the optical polarization modulation allows significant attenuation of the PMD component

Linearly single polarization fibers with zero polarization mode dispersion

IEEE Journal of Quantum Electronics, 1982
The optimum waveguide structure for linearly single polarization fibers, which satisfies the large modal birefringence and the zero polarization mode dispersion simultaneously, has been investigated. The basic waveguide structure is the single-mode optical fiber that has an elliptical core and stress-applying parts with a different expansion ...

Polarization mode dispersion measurement based on continuous polarization modulation

Applied Optics, 2008
A novel technique is proposed for measurement of the group delay (GD) and the differential group delay (DGD) of optical material, components, and fiber. This new method is based on continuous polarization modulation of the stimulus optical field as opposed to sequential polarization state switching used in the traditional phase shift method.

Polarization mode dispersion for single-mode fibers with polarization dependent losses

Optics Communications, 1993
Birefringent single-mode fibers with random polarization mode coupling and polarization dependent losses are considered. The effect of these losses on polarization mode dispersion (PMD) is computed. The relevant number is found to be the differential loss between both polarization modes over one coupling length.

Polarization mode dispersion in a single mode fiber

Journal of Lightwave Technology, 1996
The Jones matrix method is used to measure the polarization mode dispersion (PMD) of a large variety of single mode fibers in the 1500 nm range. The dependence of PMD on wavelength, time, and temperature are studied in two different regimes: adiabatic and isothermal.
