Abstract: An ensemble Monte Carlo method is employed to evaluate the performance of resonant-phonon terahertz quantum cascade lasers. Based on our simulation, a device structure is designed to avoid the strong absorption of atmosphere. The material growth, structural analyses and optical characteristics of the laser are present. Using gold-gold waveguide layers, we demonstrate a device lasing at 3.4 THz, which is just located at a low-loss stage of the atmosphere.

Keywords: Terahertz, Quantum Cascade Laser, Monte Carlo.
