论文摘要
我们已经研究了量子点（QD）terahertz（THz）光学谐振器偶联系统中的光 - 物质混合激发。我们通过使用藻类/GAAS二维电子系统（2DES）在THZ拆分谐振器（SRR）附近制造栅极定义的QD。通过用THZ辐射照亮系统，QD显示了当前的变化，其光谱在QD和SRR中的电子之间表现出连贯的耦合以及2DES和SRR之间的耦合。后者耦合进入了超局势耦合方案，尽管QD中只有几个电子，但QD和SRR之间的耦合也非常接近Ultrastrong耦合方案。
We have investigated light-matter hybrid excitations in a quantum dot (QD)-terahertz (THz) optical resonator coupled system. We fabricate a gate-defined QD in the vicinity of a THz split-ring resonator (SRR) by using a AlGaAs/GaAs two-dimensional electron system (2DES). By illuminating the system with THz radiation, the QD shows a current change whose spectrum exhibits coherent coupling between the electrons in the QD and the SRR as well as coupling between the 2DES and the SRR. The latter coupling enters the ultrastrong coupling regime and the coupling between the QD and the SRR is also very close to the ultrastrong coupling regime, despite the fact that only a few electrons reside in the QD.
