Abstract

A scheme for cascade laser based on optical transitions between resonant states of shallow impurities in selectively doped superlattices is discussed. The inverse population mechanism is provided by the possibility of varying the lifetimes of the working states on the basis of hybridization of subbands with spatially separated wave functions. The conditions in which the ground state of an impurity in one of the quantum wells is close to the bottom of the subband in the neighboring well are analyzed.
