Quantum cascade lasers (QCLs) provide the most intriguing design for quantum engineering and show how artificial materials with tailored properties can be produced through quantum design. Their inherent quantum nature conceptually affects their core concepts. QCLs actually exhibit intrinsic linewidths that approach the quantum limit, and are locked into their own states. Minimized metrology also works in the boundary frequency domains as far. In this paper, the effect of temperature on the characteristics of GaN/AlGaN and GaAs/AlGaAs quantum cascade lasers in the terahertz range is done based on rate equations. The temperature dependence of the phonon sputtering rate, changes in line width and lifetime of thermoion emission have been investigated, and also the effect of temperature on the photon lifetime in two materials, GaAs and GaN, has also been investigated and compared, and the effect of temperature on the output photon density, power and gain The unsaturated mode and its dependence on temperature show that GaN material can work at high temperatures.
