Effects of resonant tunneling on intrinsic linewidth of quantum cascade lasers

The quantum Langevin analysis for QCLs show that coupling strength and dephasing rate strongly affect the linewidth of THz QCLs in incoherent resonant-tunneling transport regime, but induce insignificant influence for mid-infrared QCLs due to strong coupling.
