Abstract :
We present a theoretical study of structure dependent effects on carrier dynamics in simulated pump probe experiments of quantum-well optical amplifiers. We find that the dynamics of the unconfined carriers alter the probe transmission. We show that local capture has an effect which is similar to that of carrier cooling, and that by taking into account the carrier induced waveguide loss in a dynamic fashion, we can explain a previously measured transmission overshoot
