A quantum cascade laser (QCL) thermal model is presented. The model is used to calculate the active region temperature of an InGaAs/AlAsSb QCL under a range of operating conditions and device geometries. The active region temperature is a limiting factor of QCL performance and knowledge of the thermal dynamics inside these devices is crucial in order to improve their temperature performance. Buried heterostructures (BH) are found to offer the best thermal performance, allowing higher heat sink temperatures than alternative device geometries under both pulsed and continuous-wave (CW) operating conditions.
