Rate equation-based phase recovery for semiconductor laser coherent transmitters

• We present a novel carrier recovery technique for coherent systems with semiconductor lasers that incorporates the laser dynamics. A sensitivity improvement of 8dB over a decisiondirected phase-locked loop is achieved experimentally for 28GBd DP-16QAM.
