Abstract

This study investigates the properties of exciton-polaritons in a 2D hybrid organic-inorganic perovskite microcavity in the presence of optical Stark effect. Through both steady and dynamic state analyses, strong coupling between excitons of perovskite and cavity photons is revealed, indicating the formation of polaritons in the perovskite microcavity. Besides, it is found that an external optical Stark pulse can induce energy shifts of excitons proportional to the pulse intensity, which modifies the dispersion characteristics of the polaritons.

存在光学斯塔克效应的二维有机-无机混合包晶微腔中的激子-极化子

本研究探讨了存在光学斯塔克效应的二维有机-无机混合包晶微腔中激子-极化子的特性。通过稳态和动态分析，发现了包晶的激子与腔光子之间的强耦合，表明在包晶微腔中形成了极化子。此外，研究还发现外部的斯塔克光脉冲能诱导激子发生与脉冲强度成正比的能量移动，从而改变了极化子的色散特性。
