And experimentally, the thermal stability has been proved dependent on the number of active quantum dot layers (QDL), which is difficult to be explained by the conventional confinement theory. This work theoretically investigates the physics of thermal stability of InAs/InGaAsP/InP QD lasers, using the combination of time-domain travelling-wave (TDTW) methodology and the 8-band [[EQUATION]] method. The threshold current, output power and peak wavelength shift are considered in this work. It is found that, within QD active medium, carrier evaporation dominantly affects the temperature-dependent behaviors of QD laser compared with other carrier motions such as carrier capture and Auger recombination. The evaporation process hinges on carrier escape times from the ground states (GS) to the excited states (ES) and from the wetting layer (WL) to the separate confinement heterostructure (SCH). Further, adjusting QDL modifies carrier escape times, thus leading to change of thermal stability, particularly affecting threshold current and output optical power. On the contrary, wavelength shifts remain unaffected by carrier evaporation, instead being influenced by temperature-induced perturbations in the GS bandgap.
