The authors compare the threshold current density jth against the laser length of a single layer quantum dot (SLQD) laser with a sixfold multilayer quantum dot (MLQD) laser. Gain saturation is not observed in the MLQD laser. They calculate jth against the number of dot layers including gain saturation. The strong impact of thermal coupling of carriers on jth is demonstrated
