Anisotropic 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 ...

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 کاملBirefringence in Optical Fibers: Applications
As discussed in the previous chapter, the so-called single-mode fibers in fact support two modes simultaneously, which are orthogonally polarized. In an ideal circular-core fiber, these two modes will propagate with the same phase velocity; however, practical fibers are not perfectly circularly symmetric. As a result, the two modes propagate with slightly different phase and group velocities. F...
