Monte Carlo study of intrinsic linewidths in terahertz quantum cascade lasers

Christian Jirauschek
Based on a coupled simulation of carrier transport and optical cavity field, the intrinsic linewidth in resonant phonon terahertz quantum cascade lasers is self-consistently analyzed. For high power structures, values on the order of Hz are obtained. Thermal photons are found to play a considerable ... [Opt. Express 18, 25922-25927 (2010)]
