Towards Quantum Plasmonics on a Chip: An Efficient Photon-Plasmon-Coupler for Single-Mode Operation — •Günter Kewes1, Andreas W. Schell1, Rico Henze1, Sven Burger2, and Oliver Benson1 — 1Institut für Physik, Humboldt-Universität zu Berlin — 2Konrad-Zuse-Zentrum für Informationstechnik Berlin
Not only the ability of surface plasmon polaritons to guide energy and information below the diffraction limit of light [1] but also their quantum nature [2], hold great potential for highly integrated photonic/plasmonic circuits or on-chip experiments. We numerically investigate and design a photon to plasmon coupler which consists of a tapered dielectric waveguide and a V-shaped metal part, using adaptive finite-element methods. We pay special attention on an easy-to-fabricate approach and focus on single-mode operation since this will simplify quantum plasmonic experiments.
