Abstract

This paper proposed a novel algorithm to obtain a wanted amplifier gain spectrum in order to get a flat gain within a wide gain band for the first time. In this method three pumps with different power and frequency space are composed to one pump unit which is optimized with a pre-specified gain ripple. We have been able to generate an optimum compensated spectrum for the EDFA or FOPA in less than 50 iterative optimizing steps resulting in less than 0.5dB gain ripple.
