Pulse broadening in optical fiber with polarization mode dispersion and polarization dependent loss

摘要

The pulse broadening of optical signals in a single mode fiber was studied theoretically in presence of polarization mode dispersion, polarization dependent losses, chromatic dispersion, and spectral chirping. Analytical expressions were derived for the parameters of pulse broadening characteristics without simplification assumptions with respect to the pulse shape and to the order of dispersion. Comparisons with the published theoretical work by numerical simulation showed the compatibility and capability of the expressions.
