我们测量了光子晶体板的亚皮秒光致透射变化，其中嵌入了无机-有机层状钙钛矿半导体，以获得大的光学非线性。观察到在泵浦脉冲的照射期间，尖锐的透射骤降向蓝移。这一结果解释了激子光学斯塔克效应引起的极化激元色散关系的变化。讨论了超快光开关的可能应用。(C)2002年美国物理学会。
We have measured the subpicosecond photoinduced transmission change of the photonic crystal slab, in which inorganic-organic layered perovskite semiconductor is embedded for large optical nonlinearity. It is observed that sharp transmission dips shift to the blue during the irradiation of the pump pulse. This result is explained in terms of the change of the polariton dispersion relation due to the excitonic optical Stark effect. Possible application for ultrafast optical switching is discussed.
