11 June 2003 Ultrafast switch-off of an electrically pumped InAs/GaAs quantum dot laser

This paper reports on transient switch-off of the emission of an electrically pumped quantum dot laser with perturbation by a short optical pulse. This laser response is explained in terms of hot carrier absorption on intraband optical transitions leading to the transient suppression of the laser mode and, hence, to the switch-off. The switching time constant is determined to be as fast as 2 ps.
