Abstract
The authors propose two novel sources emitting in the mid-IR: type-II and type-I interband cascade lasers, and perform detailed gain calculations. High radiative efficiencies are expected, since the phonon processes which dominate relaxation in the intersub-band quantum cascade laser are effectively eliminated.Keywords
