We demonstrate, theoretically and experimentally, a polarization-controlled optical gate based on a degenerate polariton-polariton scattering process occurring in semiconductor microcavities. Because of the interference between coherent polaritons, this process is observed in the case of polaritons generated from two collinearly polarized coherent pump beams. On the contrary, if the beams are cross polarized, the scattering is suppressed.
我们通过理论和实验证明了一种基于半导体微腔中简并极化激元 - 极化激元散射过程的偏振控制光闸。由于相干极化激元之间的干涉，在由两个共线偏振的相干泵浦光束产生的极化激元情况下观察到该过程。相反，如果光束是交叉偏振的，则散射受到抑制。
