Abstract
The coupling of light to surface plasmons (SPs), the collective oscillations of electrons on metal surface, makes it possible to miniaturize photonic devices beyond diffraction limit of light and enables the manipulation of light-matter interaction at the nanometer scale. Chemically synthesized Ag nanowires (NWs) with crystalline structures and smooth surfaces are excellent waveguides that support propagating SPs, and can be easily manipulated to construct complex optical devices, which make them ideal candidates for proof-of-principle studies for plasmonic circuits. Moreover, surface plasmons provide the ability to enhance the weak interaction between individual quantum emitters and photons for quantum information applications. The generation of single plasmons by coupling Ag NW with single quantum emitters opens the prospects of using quantum optical techniques to control single SPs and designing novel quantum plasmonic devices. Here we study the controllable SP propagation in Ag NWs and the coupling between a Ag NW and individual quantum dots.
