Broadband CW pumped fiber optical parametric amplifier with 49 dB gain and wavelength conversion efficiency

Abstract

Broadband, CW pumped fiber-based parametric amplifier with 49 dB of internal gain and wavelength conversion efficiency, corresponding to a net gain/efficiency of 38 dB, is demonstrated. BER measurements indicate performance comparable to EDFAs. These amplifiers may thus find new applications in future lightwave systems.
