ZENG Zhi~1, YU Chong-xiu~1, LIU Lei~1, et al. Comparisons of control signals in adaptive PMD compensators[J]. 2005,(4):39-41. DOI: 10.13756/j.gtxyj.2005.04.013.
We compared feed forward and feedback as control mechanisms in adaptive polarization mode dispersion compensators(APMDC); Different signals work as control input of APMDC
such as degree of polarization
spectral frequency component
eye-opening penalty
phase difference between frequency components on the orthogonal principal states of polarization
