Abstract
The authors compare the threshold current density j(th) against the la ser length of a single layer quantum dot (SLQD) laser with a sixfold m ultilayer quantum dot (MLQD) laser. Gain saturation is not observed in the MLQD laser. They calculate j(th) against the number of dot layers including gain saturation. The strong impact of thermal coupling of c arriers on j(th) is demonstrated.
