Abstract

Large optical nonlinearities have been observed in molecular beam epitaxially grown thin films of ZnSe at room temperature and at T=150 K. A comparison with a plasma theory indicates that in both cases exciton screening is the dominating mechanism for the nonlinearity. The maximum nonlinear index per excited electron-hole pair at room temperature is comparable to that of bulk GaAs and GaAs-AlGaAs multiple quantum wells. The measured absorption and nonlinear index spectra agree quite well with our calculated values.
