J. Hansryd et Pa. Andrekson, Broad-band continuous-wave-pumped fiber optical parametric amplifier with 49-dB gain and wavelength-conversion efficiency, IEEE PHOTON, 13(3), 2001, pp. 194-196
A broad-band continuous-wave (CW) pumped fiber-based parametric amplifier w
ith 49 dB of internal gain and wavelength conversion efficiency, correspond
ing to a black box gain/efficiency of 38 dB, is demonstrated. Bit-error-rat
e (BER) measurements indicate performance comparable to erbium-doped fiber
amplifiers (EDFAs), These amplifiers may thus find new applications in futu
re lightwave systems.
