Picosecond optical bistability in ZnCdSe/ZnSe multiple quantum wells at room temperature

摘要

Abstract: The picosecond optical bistability of Zn$-1$MIN@x$/Cd$-x$/Se/ZnSe (x $EQ 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.!4
