Low-noise phase-sensitive amplifier for guard-band-less 16-channel DWDM signal using PPLN waveguides

A X(2)-stage SHG/OPA configuration enabled low-crosstalk and guard-band-less DWDM signal amplification. We demonstrated a 5.6-dB link-SNR improvement and a low NF of 2.1 dB below the 3-dB quantum limit in simultaneous 16-channel-signal amplification.
