Abstract
The behaviour of InAs/GaAs quantum dot lasers (QDL) emitting at 1.3 µm under the influence of external optical feedback has been studied. A threshold for coherence collapse of −8 dB has been measured. This very high threshold has been explained as a consequence of high relaxation oscillation damping in these lasers.
