ABSTRACT:
The phenomenon of polarization jitters caused
by fiber nonlinearity is investigated. A general formula
about the polarization jitter is concluded in polarization multiplexing (PM)
system based on two orthogonal linear polarization states when the best
polarization correction is used. A 100 Gb/s PM system based on NRZ code is
investigated by simulation, and the Stocks parameter about polarization jitter
and Poincare sphere diagrams are got for different power and phase difference
of two orthogonal polarized light. The results show that the polarization
jitters will be suppressed when the combined PM signal is the linear or circular
polarization state.
