Polarization decorrelation in optical fibers with randomly varying birefringence.
Polarization decorrelation in single-mode fibers with randomly varying birefringence is studied. We find that decorrelation length is minimized for a given beat length if the average autocorrelation length of the birefringence is close to the average beat length. The differential time delay between the polarization modes is found to depend on the autocorrelation length of the birefringence rath...
متن کاملPolarization decorrelation in optical fibers with randomly varying elliptical birefringence.
Polarization decorrelation in single-mode fibers with randomly varying elliptical birefringence is studied. It is found that the effects of ellipticity on the polarization decorrelation length depend on the relative sizes of the beat length and the autocorrelation length of the birefringence fluctuations in the fiber. However, the evolution of the differential group delay remains unaffected by ...
متن کاملPolarization mode dispersion of spun fibers with randomly varying birefringence.
We show analytically how periodic spinning affects the polarization mode dispersion of a fiber in three different practical regimes that are determined by the values of three length scales: the beat length, the birefringence correlation length, and the spin period. We determine in which limits the spin is effective in reducing the mean differential group delay.
متن کاملAnisotropic diffusion of the state of polarization in optical fibers with randomly varying birefringence.
Random fluctuations in birefringence along an optical fiber degrade the transmission rate in communication systems. In modern, dispersion-shifted communication fibers, at typical data rates and transmission powers, the birefringent beat length is of the order of meters or tens of meters, whereas the dispersive and nonlinear scale lengths are typically hundreds of kilometers. Thus, although the ...
متن کاملRadiation-induced interaction of optical solitons in fibers with randomly varying birefringence.
We study propagation of solitons in optical fibers with randomly varying birefringence which results in polarization mode dispersion. Due to the disorder, solitons emit radiation, i.e., the energy of the solitons is partly transferred into the delocalized modes. The radiation serves as a mediator of the intersoliton interaction leading to fluctuations of the soliton separations. We establish st...
