Abstract :
We experimentally demonstrate nondegenerate phase-sensitive amplification of a 40-Gb/s differential phase-shift-keying data signal in both single- and double-pumped parametric configurations. Careful optimization of the system has allowed a uniform phase-sensitive gain and attenuation to be achieved over at least 20 nm of bandwidth.
