Frascella, Paola, Sygletos, Stylianos, Garcia Gunning, Fatima C., Weerasuriya, Ruwan, Grüner-Nielsen, Lars, Phelan, Richard, O'Gorman, James and Ellis, Andrew D. (2011). DPSK signal regeneration with a dual-pump nondegenerate phase-sensitive amplifier. IEEE Photonics Technology Letters, 23 (8), pp. 516-518.


We demonstrate, for the first time to our knowledge, regeneration of a 42.66-Gb/s differential phase-shift keyed signal using a dual-pump nondegenerate four-wave-mixing-based fiber-optic parametric amplifier. The regenerative performance of the subsystem is characterized in terms of bit-error rate against narrowband and wideband introduced noise. While a strong receiver sensitivity improvement, up to 20 dB, is noticed against narrowband noise, against quasi-random (wideband) noise we observe a regeneration of 2.7 dB.
