摘要：

We have demonstrated highly repetitive picosecond polarization optical switching operation of type-II quantum well structures at room temperature. The switching mechanism is due to the fast GAMMA-X interlayer scattering of electrons and the fast spin relaxation of holes. According to our experimental results, the switching time is less than 1 ps, the switching power is as low as 3 nJ/cM2, and the switching repetition rate is more than 80 GHz. Moreover we point out the possibility of continuous optical switching operation for future applications.
