40 Gb/s optical demultiplexing with amplitude regeneration based data pump FOPA

Abstract

40 Gb/s optical demultiplexing with amplitude regeneration is demonstrated based on data pump fiber-optical parametric amplification while a 10 GHz short pulse is used as the probe. Four 10 Gb/s output channels with at least 14 dB extinction ratio enhancement and an average 5.5 Q factor is obtained after demultiplexing.
