| 摘 要： | 用MOCVD在CaF_2衬底上生长的ZnSe/ZnS多量子阱材料,在77K下用N_2激光泵浦染料获得的宽带光脉冲进行了非线性光学测量,首次观察到ZnSe/ZnS多量子阱的激子光学双稳性,据分析这是由激子的能带增宽效应引起的增强吸收光学双稳性.

| Abstract: | Optical bistability in the ZnSe/ZnS multiple quantum wells (MQWs) grown by MOCVD has been observed at 77 K for the first time with ns switching time. On the bases of the shape of hysteresis loop and photoluminescence and absorption spectrum measured, the optical bistability in the ZnSe/ZnS MQWs can be attributed to enhanced absorption effect, which originated from the collision broadening of excitonic resonance. |
