ND-PSA repeaters using recovered pump generated from PCTWs is proposed. Calculations show proposed repeaters enables over 76-span transmission of 20-Gbit/s QPSK PCTWs, and phase-synchronization using(More)
Optical phase-locking among 5-Gbit/s BPSK phase-conjugated twin waves and a free-funning pump is experimentally demonstrated. A sum-frequency and second harmonic generation assisted OPLL circuit(More)
