Fundamental limits in the wallplug efficiency of quantum cascade lasers are derived in a rate equation model that uses global effective parameters. Free carrier absorption and thermal population of the lower state force a strong downward trend of this efficiency with increasing wavelength, that agrees well with experimental data taken from literature.

- Next-generation mid-infrared sources (2017, background): “The ∼ps timescale nonradiative lifetimes associated with QCL ISB optical transitions lead to large threshold current densities (Jth), which limit the wall-plug efficiency of the QCL [41], and lead to weak sub-threshold emission.”
