Stimulated and spontaneous emissions in Zd0.8Cd0.2Se-ZnSe strained layer superlattice with Fabry-Perot cavity

The transformation from stimulated to spontaneous emissions at 77K is performed in Zn0.8Cd0.2Se-ZnSe strained layer superlattice (SLS) with Fabry-Perot cavity. It is found that the lasing oscillation modes disappear and the stimulated emission is transformed into the amplified spontaneous emission owing to the phase space filling effect of exciton states under higher excitation density.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
