Abstract
In this work, we demonstrate the implementation of a low cost broadband pump source for Raman
amplification. The advantages of this incoherent pumping scheme were demonstrated by comparing,
experimentally and numerically, this solution with the one based on coherent pumping. We
observed a decrease by 1.4 dB in the Raman gain ripple and a 16% increase in the bandwidth, for
the latter solution.
