The Output DOP Influenced by PMD, PDL and Chirp
2008
The output
degreeof
polarization(DOP) can be seriously influenced by polarization dependence loss (PDL) and
polarization mode dispersion(PMD). We develop a mathematical description to study the output DOP influenced by PMD, PDL and
chirp. The exact character of DOP is simulated with a two-
concatenated-fiber model in the presence of PMD, PDL and
chirp. Simulation results show that the output DOP may change with PDL even if PMD is invariable. On the other hand, the
chirpof the pulse itself may affect the DOP of the output light. The exact influence by PDL and
chirpcan be decided by parameter γ2.
