Abstract: Abstract A polarization diversity-based PON system can be an attractive network solution for the future PON system that requires high data capacity with both a large number of subscribers and longer transmission-reach. However, the state-of-polarization… read more here.

Abstract: We propose to track state of polarization (SOP) rotation by utilizing chirp pilots processed through fractional Fourier transform (FrFT). Superimposed on dual-polarization data signal, the chirp pilots with different FrFT rotation orders can converge to… read more here.
