用实空间方法研究了由半导体量子点(SQD)和金属纳米粒子(MNP)组成的混合系统与一维表面等离子体波导单等离子体相互作用的输运特性。我们认为，MNP-Sqd相互作用导致混合激子的形成，通过调节应用于MNP-Sqd混合纳米系统的经典控制场的频率、MNPs的种类和背景介质，可以控制单入射等离激子的传输和反射。本文所讨论的单等离激元与这种混合纳米系统相互作用的输运性质可能会在下一代量子器件的设计中得到应用，例如单光子开关和纳米误差，以及在量子信息处理中的应用。
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.
