Coherent PM Optical Link Employing ACP-PPLL

摘要

This paper concerns the modeling, design, and experimental validation of coherent phase modulated RF/optical link employing an ACP-PPLL linear phase demodulator. From theoretical modeling, the closed-form solutions for link gain, noise figure, and SFDR are derived. Then, two examples of link design are addressed: one with 100-MHz and one with 500-MHz bandwidth. Finally, experimental validation was performed using the 100-MHz design. The experimental results are in good agreement with the theoretical prediction.
