“…In the limit of small PMD we get b 2 unc = 1 + 2x/3 because only 2 of the 3 orthogonal directions in Stokes space causes broadening (the two orthogonal to the PSPs). This will also cause the pulse width to be Rayleigh (rather than Maxwell) distributed in this limit, as found numerically in [20] and explained theoretically in [21].…”

“…Both DOP and eye opening penalty (EOP) are calculated at the receiver end for system performance evaluation. A long transmission fiber can be modeled as a concatenated series of linearly birefringent segments with statistically varying group delays and orientations of the birefringence axes [13]. At every junction between two segments, the energy from each incident pulse is split into two orthogonally polarized pulses, representing the mode coupling that occurs in the fiber due to perturbations in local birefringence.…”

The optimal length of the fixed delay line (FDL) for a one-stage optical polarization mode dispersion (PMD) compensator with two degrees of freedom (DOF) is investigated for a 40 Gbit/s NRZ optical fiber transmission system by implementing genetic algorithm in the logic-control unit. It is found that there exists an optimal length of FDL for such an optical PMD compensator (PMDC), and the optimal length of the FDL is equal to the PMD value of the preceding transmission fiber to be compensated for. Such an optimized one-stage PMDC with a fixed delay line can achieve a close performance to that of a one-stage PMDC with a variable delay line.

“…Finally, we simulated 14 Figure 9 shows the narrowed pulse obtained for such a fiber when its mean 15 DGD equals 35 ps. In this case it was possible to obtain a sharp reduction of the pulsewidth, of 9.018 ps, at the expense of high power loss.…”

Pulse narrowing in optical components with polarization mode dispersion using polarization controls

et al. 2000

An algorithm capable of finding the input and output states ofpolarization for maximum pulse narrowing at the output of an optical fiber with polarization mode dispersion (PMD) is analytically presented and numerically solved. It is always possible to obtain output pulses which are narrower than the input pulses when PMD is compensated by controlling both the input polarization as well as the receiver polarization states. This anomalous effect was shown to be exclusively due to PMD as no chromatic dispersion or polarization dependent losses were assumed. We report the detailed study for the cases in which the fiber consists oftwo, three and five hundred segments ofhighly-birefringent (Hi-Bi) fiber. The solution shows the existence of two orthogonal input and output states ofpolanzation (different from those introduced by Poole et. al.) under which the integrity of the pulse is preserved and the pulsewidth at the output is the narrowest possible. The cost to be paid for this improvement is a reduction ofthe optical power in the output pulse.
