In the regime with maximum linear gain in a quantum dot (QD) semiconductor optical amplifier (SOA), instantaneous gain modulation by change of the photon density is possible due to spectral hole burning effects. This, in turn, leads to the opportunity of ultrafast cross-gain modulation (XGM) without
We have performed cross-gain modulation experiments on semiconductor optical amplifiers with 100 fs pump pulses. Setting the pump on the high energy side of the gain results in a complex transient for the CW probe that is situated at gain maximum. An important part of this transient is shown to be d
