  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.
