Abstract
We show via a combination of material realistic quantum-kinetic theory and experimental differential pump-probe results, that performance issues in tunnel-injection QD lasers are caused by a filtering effect, resulting from the hybridization of different QD shells with the injector quantum well. The real footprint of applicability in optical communication system is the large signal modulation response, which, on the other hand is much less often investigated.
