The transport properties of a single plasmon interacting with a hybrid system composed of a semiconductor quantum dot (SQD) and a metal nanoparticle (MNP) coupled to a one-dimensional surface plasmonic waveguide are investigated theoretically via the real-space approach. We considered that the MNP-SQD interaction leads to the formation of a hybrid exciton and the transmission and reflection of a single incident plasmon could be controlled by adjusting the frequency of the classical control field applied to the MNP-SQD hybrid nanosystem, the kinds of MNPs and the background media. The transport properties of a single plasmon interacting with such a hybrid nanosystem discussed here could find applications in the design of next-generation quantum devices, such as single-photon switching and nanomirrors, and in quantum information processing.
通过实空间方法理论研究了与一维表面等离激元波导耦合的半导体量子点(SQD)和金属纳米颗粒(MNP)组成的混合系统中单个等离激元的输运性质。我们认为,MNP-SQD 相互作用导致形成混合激子,通过调整施加到 MNP-SQD 混合纳米系统、MNP 的种类和背景介质的经典控制场的频率,可以控制单个入射等离激元的透射和反射。这里讨论的单个等离激元与这种混合纳米系统相互作用的输运性质可以应用于下一代量子器件的设计,例如单光子开关和纳米镜,以及量子信息处理。
