Robust Multilevel Coherent Optical Systems With Linear Processing at the Receiver

  title={Robust Multilevel Coherent Optical Systems With Linear Processing at the Receiver},
  author={Giulio Colavolpe and Tommaso Foggi and Enrico Forestieri and Giancarlo Prati},
  journal={Journal of Lightwave Technology},
This paper investigates optical coherent systems based on polarization multiplexing and high-order modulations such as phase-shift keying (PSK) signals and quadrature amplitude modulations (QAM). It is shown that a simple linear receiver processing is sufficient to perfectly demultiplex the two transmitted streams and to perfectly compensate for group velocity dispersion (GVD) and polarization mode dispersion (PMD). In addition, in the presence of a strong phase noise of the lasers at the… CONTINUE READING
