TLDR
In this paper, an adjustable polarization-mode-dispersion (PMD) compensator using a nonlinearly chirped fiber Bragg grating written into a high-birefringence photosensitive fiber is presented.Abstract:
We demonstrate an adjustable polarization-mode-dispersion (PMD) compensator. The device uses a nonlinearly chirped fiber Bragg grating written into a high-birefringence photosensitive fiber. By mechanically stretching the grating, the device generates a time delay between different polarizations that is adjustable from 100 to 320 ps and is tunable over 2.3 nm. We demonstrate tunable PMD compensation of a 10-Gb/s signal that has an initial delay between the two polarization states of 127 or 302 ps.read more

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.

Theoretical and experimental study on PMD-supported transmission using polarization diversity in coherent optical OFDM systems.
TL;DR: It is shown that the optical fiber channel model can be treated as a special kind of multiple-input multiple- output (MIMO) model, namely, a two-input two-output (TITO) models which is intrinsically represented by a two -element Jones vector familiar to the optical communications community.

Polarization mode dispersion compensation by phase diversity detection
TL;DR: In this article, a phase diversity detection method for compensating for polarization mode dispersion (PMD) in optical fiber at 10 Gb/s is described. But this method relies on a three-sectioned polarization maintaining fiber that provides a controlled amount of PMD in the range of 1.6-42 ps.

TL;DR: The results suggest that photoionization is not needed for formation of gratings in Ge-doped glass and an enhancement of the 334-nm photosensitivity in boron-codoped fibers is observed and it is suggested that B facilitates a structural transformation of the glass.
