摘要：

Optical and electrical tuning of the propagation time of 170 fs pulses in a quantum dot semiconductor amplifier at room temperature is demonstrated. Both pulse slowdown and advancement is possible and we achieve fractional delays ( delay divided with pulse duration) of up to 40%. The results are explained by a simple gain saturation model.
