Nonlinear Dynamics in Semiconductor Lasers - Abstract
Huyet, Guillaume
In this work, monolithic passively mode-locked lasers, based on InAs/GaAs quantum dot material, are studied and stabilised by means of external optical injection. We demonstrate that optical injection can improve the properties of mode-locked lasers in terms of the time-bandwidth product, noise and pulse stability. Finally, a cascade of quantum dot mode-locked lasers is utilised in order to (i) clone coherence and performance characteristics of the master source and (ii) to obtain high quality wider frequency combs resulting in pulses of short duration.
