Coupling of Quantum Emitters to Localized and Propagating Plasmons

Published on

Abstract

Surface plasmon (SP) modes supported by various dielectric-metal waveguide configurations facilitate strong enhancement and (subwavelength) confinement of electromagnetic fields, enabling miniaturization of SP-based nanophotonic components and circuits while also strongly enhancing interaction of quantum emitters (QEs) with both localized and propagating SP modes. The latter feature has important implications in quantum optics, sensing and lab-on-a-chip applications. One of the main challenges in developing future nano-scale quantum photonic circuits is to manage combining on a single chip a single photon source, waveguides, modulators and detectors. In this talk, I review our latest theoretical and experimental results concerning QE coupling to localized and propagating SP modes. In particular, influence of gap SP resonators on the decay rate of closely located QEs and different decay contributions are discussed as well as the dynamics of resonant QE coupling to a localized SP that can also be used for entanglement of two qubits. Furthermore, theoretical and experimental results demonstrating deterministic coupling of the emission of a single QE (created by a nitrogen vacancy embedded in a diamond nanoparticle) to channel SP modes, which are supported by a V-shaped waveguide cut in gold, are reported. It is argued that this approach can enable realistic and functional plasmonic circuitry and therefore, paves the way towards the development of efficient and long distance transfer of energy in integrated solid-state quantum systems.

He joined the Department of Physics and Nanotechnology, Aalborg University (Denmark) in 1991, becoming a professor in physics in 2003. Since February 2008 he is a professor in nano-optics at the University of Southern Denmark (Odense), heading research activities within plasmonics and near-field optics. His research interests include linear and nonlinear nano-optics, surface plasmon polaritons and nano-plasmonic circuits, multiple light scattering including photonic band gap and light localization phenomena, photonics and optical sensors. Plasmonics with implications to nanophotonics and bio- and molecular sensing is his main current research field. He has (co-) authored more than 240 scientific publications in peer-reviewed journals (citations > 4300, h = 33), 10 patents and 9 book chapters, edited a book “Plasmonic Nano-Guides and Circuits” (Word Scientific, Singapore, 2008) and gave more than 80 invited talks at international conferences and seminars. Prof. Bozhevolnyi has supervised 8 postdocs and 15 PhD projects. He is a Fellow of the Optical Society of America and a Member of Danish Academy of Natural Sciences (DNA).
