Optical Phase Noise Extraction and Amplification Technique and its Application to Optical Phase Noise Monitoring for (D)PSK Systems

摘要

We propose an optical phase noise extraction and amplification (OPNEA) technique. By applying OPNEA to phase noise monitoring for (D)PSK, 13-dB dynamic range and 0.2-dB/degree sensitivity were achieved with a 50-120-degree phase deviation.
