Abstract:
Raman-assisted PSA without phase-stabilization-loop is experimentally evaluated by placing signals at different locations in a quasi-periodic PSA power spectrum. With phase adjustment, an 18dB peak-dip gain-extinction-ratio difference is observed. Improved performance is demonstrated using 10/20/50-Gbaud QPSK and 10-Gbaud 16QAM signals.
