摘要：
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 designing smoothly graded and stepwise-constant AlxGa1-xAs ternary alloy quantum wells. with the self-consistent potential taken into account.
