Abstract
A design of a quantum cascade laser operating at 1 THz is proposed and studied by means of ensemble Monte Carlo simulation. Starting from a resonant-phonon structure working at 2.1 THz [B. Williams, S. Kumar, Q. Hu, J. Reno, Electron. Lett. 40 (7) (2004) 431], a refinement is proposed in order to reduce the lasing frequency. Schrödinger–Poisson calculations show that frequency as low as 1 THz can be reached, by adjusting the AlGaAs barrier heights. Moreover, our Monte Carlo simulation predicts a significant population inversion.
