Abstract

We report the first experimental demonstration of parametric amplification and all-optical phase-preserving amplitude regeneration for a 640 Gbit/s return-to-zero (RZ) differential phase-shift keying (DPSK) optical time division multiplexed (OTDM) signal. In the designed gain-flattened single-pump fiber optical parametric amplifier (FOPA), 620 fs short optical pulses are successfully amplified with 15 dB gain with error-free performance and less than 1 dB power penalty. Phase-preserving amplitude regeneration based on gain saturation in the FOPA is carried out for optical signals with degraded optical signal-to-noise ratio. An improvement of 2.2 dB in receiver sensitivity at a bit-error-ratio of 10−9 has been successfully achieved after regeneration, together with 13.3 dB net gain.

(a) BER measurements for a 10 Gbit/s DPSK channel demultiplexed from the 640 Gbit/s signal. (b) Receiver sensitivity at a BER of 10−9 in back-to-back configuration. (c) Eye-diagrams of demultiplexed and demodulated signals for back-to-back and after amplification with −10 dBm and +6 dBm input power.
