摘要：

We describe time-resolved chirp measurements in InAs/InP quantum-dash optical amplifiers operating at 1550 nm. We highlight the roles of gain saturation and of the saturating pulse duration relative to the gain recovery time. Using 10 Gbit/s data, we demonstrate a low transient alpha parameter of less than one which causes negative chirp at the leading edge and positive chirp during the trailing edge of the input pulse.
