Recently, there have been reports that the optical gain in CdZnSe QW lasers is not derived from stimulated processes between free electrons and holes but between bound electron and holes or excitons. If so, then an "excitonic gain" (EX) model rather than the electron-hole plasma (EHP) model would be appropriate for designing CdZnSe QW lasers. While this may be the case, it is interesting at this time to see how well the EHP model can do in predicting the temperature dependence of threshold current density for such lasers. The laser structure studied has an Cd/sub 0.2/Zn/sub 0.8/Se single quantum well (65/spl Aring/) active layer.<>
