Abstract

Randomly varying birefringence leads to nonlinear polarization-mode dispersion (PMD) in addition to the well-known linear PMD. Here, we calculated the variance of the field fluctuations produced by this nonlinear PMD. The effects of fiber nonlinearity, linear PMD and nonlinear PMD are studied numerically using the Manakov-PMD equation which models signal propagation in optical fibers with randomly varying birefringence. Nonlinear PMD is shown to be unimportant in present day communication systems.KeywordsOptical FiberPolarization Mode DispersionLightwave TechnologyDispersion LengthBeat LengthThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
