Low cost incoherent pump solution for Raman fiber amplifier

Rocha A. M., Neto B., Facao M., Andre P. S.

Vol. 39, nr 2

287-293

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 compar-ing, 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.
