Abstract: In this paper, we present the effects of temperature and doping density on the performance of midinfrared quantum cascade lasers of three-level system based on rate equation. With taking into account the thermally activated population of the lower and upper lasing states. The theoretical study based on rate equation model leads to evaluation the dependence of the threshold current density and output power with temperature and sheet doping density with ns  4.1, 5.2 and 6.5  1011 cm – 2. This model allowed us to evaluate the shift of the energy difference between the upper and lower state with the variation the doping density. The results also show that output power is decreased when the temperature and the doping density are increased. The obtained results by the theoretical calculations are in good agreement with the experimental data, the results obtained from this study can be useful to improve the performance of the quantum cascade lasers.
