A method is described for the optimized design of quantum-well structures, with respect to maximizing the stimulated gain in optically pumped intersubband lasers. It relies on applying the supersymmetric quantum mechanics to an initial Hamiltonian. The use of this procedure is demonstrated by design
The optical gain of unstrained non-abrupt GaAs=AlxGa1-xAs single quantum wells as a function of the energy of the radiation, width of the well, and interface thickness is calculated. Both the transversal electrical and the transversal magnetic light polarization are considered. All sub-bands transit
## Abstract In this article, theoretical calculation of optical gain has been performed for IVβVI lead salt PbSe/Pb~1β__x__~Sr~__x__~Se quantum well lasers emitting at about 4β6βΒ΅m by using an analytic gain expression. The reduced density of states and interband transition matrix elements used in t
