Effects of resonant tunneling and dynamics of coherent interaction on intrinsic linewidth of quantum cascade lasers

A theoretical model for calculation of the intrinsic linewidth of QCLs is built on the basis of the quantum Langevin approach. It differs from the traditional rate equation model in that the resonant tunneling and the dynamics of coherent interaction can be considered. Results show that the coupling...
