Switching and Fano resonance via exciton-plasmon interaction

doi:10.1088/1674-1056/23/6/067302

Abstract We further study theoretically the properties of switching and Fano resonance in a hybrid nanosystem consisting of two quantum dots (QDs) and a metal nanowire via exciton-plasmon interaction. The transmission of the single plasmon can be switched on or off in a wide-frequency region by adjusting the transition frequencies of the QDs and the phase of the propagating plasmon. Specifically, the dynamical mechanism of Fano-type transmission is further revealed and analyzed in detail.
