Excitonic gain and stimulated emission in ZnSe-based quantum wells

Abstract

One of the potentially important technological applications of wide-gap II-VI compound semiconductor superlattices and quantum wells are lasers and related optical devices in the blue- green region. Progress has been made recently with ZnSe-based heterostructures in optical- pumping experiments, which have shown pulsed room-temperature laser action from multiple as well as single quantum wells.1,2 However, in these initial observations for (Zn, Cd)Se/ ZnSe quantum wells, the spectral details of the stimulated emission, especially at low temperature, have suggested that free excitons are important in providing optical gain and supporting laser action, in strong contrast to the usual electron-hole plasma commonly encountered, e.g., in GaAs quantum wells. At the same time, the (Zn, Cd)Se/ZnSe quantum wells have also been found to exhibit strong excitonic absorption features, which in the quasi-2-D case are well preserved up to room temperature.3 Here we present results of measurements that show such evidence for the excitonic gain and its evolution from the state of absorption saturation in the (Zn, Cd)Se/ZnSe quantum wells.
