Electric field controlling a single Plasmon transport in a metal nanowire

We investigate theoretically electrically controlling a single plasmon transport properties in a metal nanowire based on strong coupling between the guide plasmon and a quantum-dot molecule. The calculations reveal that one can control the plasmon transport properties by suitably varying the electric field. The phase shift imposing on the reflected plasmon is also analyzed.
