Solitons and polarization mode dispersion

Optics Letters, 2000
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.

Polarization mode dispersion in single-mode fibers

Optics Letters, 1978
In real single-mode optical fibers, imperfections cause the two possible polarizations to propagate at different phase velocities. This birefringence leads to different group velocities. We have measured the resulting mode dispersion in short fiber lengths (0.5-2.5 m) from the depolarization of broad-bandwidth light. In a typical fiber we found 30 psec/

Jones matrix of polarization mode dispersion

Optics Letters, 1999
We describe how to calculate the Jones matrix transfer function of a fiber if its principal states of polarization and its differential group delay as functions of frequency are known. Using two counterexamples related to second-order polarization mode dispersion (PMD), we also show that a previous method used for the same purpose induces ...

Polarization mode dispersion in a coil of single-mode fiber

Optics Letters, 1985
Polarization mode dispersion resulting from lateral stress by bending is measured as a function of bending curvature. The magnitude of the modal dispersion is found to be 286 psec/km for a bending radius of 2.8 mm. The experimental result is in good agreement with that predicted theoretically for bulk material.

Autocorrelation function of the polarization-mode dispersion vector

Optics Letters, 1999
We derive, for what is believed to be the first time, the autocorrelation function (ACF) of the polarization-mode dispersion (PMD) vector, which gives information on the bandwidths of the principal states of polarization. We compare the ACF with measured data and find good agreement.

Statistics of the polarization mode dispersion dynamics

Optics Letters, 2007
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.
