While quantum cascade lasers (QCLs) based on quantum wells (QWs) continue to be an active research topic, there have also been steps toward QCLs consisting of quantum dots (QDs). For instance, midinfrared photodetectors using QDs, including midinfrared electroluminescence at low and more recently, also in room temperature (Ref. [1,2]) have been demonstrated. The present contribution investigates the possibility of reduced threshold currents for QD based QCL active materials in the framework of a microscopic model for electrically pumped QDs.
