Transport Properties of a Single Plasmon Interacting with a Hybrid   Exciton of a Metal Nanoparticle-Semiconductor Quantum Dot System Coupled to   Plasmonic Waveguide
  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 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 metallic nanoparticles and the background media, respectively. The transport properties of a single plasmon interacting with such a hybrid nanosystem discussed here could find the applications in the design of next-generation quantum devices such as single photon switching and nanomirrors, and in quantum information processing.
