Phase-noise tolerance of optical 16-QAM signals demodulated with decision-directed carrier-phase estimation

Phase-noise tolerance of 10-Gsymbol/s 16-QAM signals is investigated both theoretically and experimentally. Optimizing the decision-directed phase-locked loop for carrier-phase estimation, we can obtain acceptable BER performance when the laser linewidth is in the 100-kHz range.
