Design of a Phase Sensor Applied in the Optical Phase-Locked Loop Based on a High-Speed Coherent Laser Communication System

The background of our research is, designing a precise phase detection sensor for high-speed coherent homodyne systems, and combining it with optical phase-locked loops (OPLLs) to achieve coherent demodulation and carrier recovery. For existing phase sensors, there are problems, such as low phase ga...
