Abstract :
We report the first experimental measurement of resonances in four-wave mixing (FWM) fields caused by lumped amplification in wavelength-division-multiplexed systems. Our numerical model allows us to predict the FWM characteristics in great detail. We also show that the FWM is reduced by more than 20 dB when two channels are launched with orthogonal polarizations.
