Figure

Fig. 1. Sketch of the carrier dynamics model, including a direct relaxation channel.
Fig. 3 illustrates the turn-on delay properties for various injected currents. With the increase of the pump current, the delay time becomes shorter which means that the carrier lifetime is decreased [29]
Fig. 8. Comparisons of damping factors calculated from the QD model and the QW model.
