The intrinsic narrow linewidth of quantum cascade lasers (QCLs) promises wide applications such as highsensitive trace-gas detection. However, so far limited work has been reported in intrinsic linewidth characteristics of QCLs. In this paper, we theoretically investigate the linewidth broadening ca...
