Carrier recovery techniques for semiconductor laser frequency noise for 28 Gbd DP-16QAM

• We report on the first experimental comparison of DD-PLL, two-stage feed forward, and two variations of extended Kalman filtering for tracking semiconductor laser frequency noise. We identify which carrier phase recovery technique works best depending on the carrier induced frequency noise profile.
