Excitonic Nonlinearities In ZnSe/ZnS Multiple Quantum Wells

Abstract

More attention should be paid on the excitonic nonlinearities of II-VI semiconductors such as ZnSe and its multiple quantum wells (MQWs) [1]-[2] because their big excitonic nonlinearities, visible wavelength operation, possibility of growing on the GaAs substrate for the potential use in nonlinear optical information processing. We present here the first study on excitonic optical nonlinearities of ZnSe/ZnS multiple quantum wells both experimentally and theoretically.
