Abstract
We compare the electronic temperatures and the electron lattice coupling in mid-infrared and terahertz GaAs-based quantum cascade lasers (QCLs). Thermalized hot-electron distributions are found in both classes of QCLs. The results illustrate the influence of the quantum design on the electron-lattice energy relaxation rates, that ultimately determine the device thermal performance.
