Temperature invariant output slope efficiency and threshold current (T0=∞)(T0=∞) in the temperature range of 5–75 °C have been measured for 1.3 μm pp-doped self-organized quantum dot lasers. Similar undoped quantum dot lasers exhibit T0=69 KT0=69 K in the same temperature range. A self-consistent model has been employed to calculate the various radiative and nonradiative current components in pp-doped and undoped lasers and to analyze the measured data. It is observed that Auger recombination in the dots plays an important role in determining the threshold current of the pp-doped lasers
