An approach is described for designing a terahertz quantum cascade laser based on AlGaAs-GaAs. Parameters such as doping concentration, which are independent of the frequency are optimally chosen. The remaining parameters are varied in order to obtain the right frequency at the best high temperature and oscillatory strength. Simulations are suitable for quantum cascade lasers structure, mainly, for calculation for its energy diagram, emission frequency, oscillatory strength and dipole moment of radiative transition. The emission of 3.5 THz is estimated based on a three-well resonant-phonon.
