Abstract
The picosecond optical bistability of Zn1-xCdxSe/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 515 nm and 530 nm. We discussed the origin of the two peaks and physical mechanism of the bistability.
