Polarization mode dispersion, decorrelation, and diffusion in optical fibers with randomly varying elliptical birefringence

In this paper, dependence of both the polarization decorrelation length and the diffusion length on the amount of ellipticity present in an optical fiber was described. A small elliptical birefringence in optical fibers yields the same differential group delay as in linearly birefringent fiber. However, ellipticity may affect the interaction of nonlinearity and polarization mode dispersion during propagation.
