The picosecond optical bistability of Zn 1-x Cd x Se/ZnSe (x equals 0.23) multiple quantum well (MQW) has been observed by a Streak Camera at room temperature for the first time. In the absorption spectra of ZnCdSe/ZnSe MQW, there are two peaks at 51

CdS-CdS1-xSex SLSs were grown on (111) GaAs substrates by MOCVD, and their characteristics were analyzed by PL measurements. Luminescence results show that the band-gap of superlattice can be controlled by changing compositions, and crystalline quali

In this letter, we have studied the multiphonon Raman scattering properties of ZnSe — 68 Cc32 Se. At room temperature the Raman spectra with various lines of Ar laser excitation are investigated. We haveobserved up to the 5th order multiphonon Rama

We have measured the nonlinear absorption change in ZnSe thin films at 77 K. The nonlinear mechanisms are attributed to the combination of the increasing absorption and the bleaching of excitons.

We have measured the nonlinear absorption and nonlinear refractive index changes in ZnSe''ZnS multiple quantum wells at low temperature. The largest change of nonlinear refractive index is 0. 012 and corresponding n2 is 7x1Ocm2IW. The nonlinear mecha
