Abstract
Time-resolved photoluminescence has been used to investigate the optic al properties of a narrow 25 Angstrom Zn0.8Cd0.2Se/ZnSe multiple quant um well structure as a function of carrier density and temperature. At low temperatures, it is found that the luminescence is excitonic over all densities up to and above threshold. The underlying gain mechanis m in cleaved 380 mu m cavities is excitonic in nature. In the low-dens ity regime, the luminescence remains excitonic up to room temperature. (C) 1998 Elsevier Science B.V. All rights reserved.
