摘要：

We have studied ultrafast gain dynamics in InGaAsP optical amplifiers by means of pump-probe and cross-correlation measurements using 180 fs optical pulses. The data show strong gain nonlinearities due to nonequilibrium carrier distributions and differ significantly from those observed in AlGaAs amplifiers.
