Abstract
Hybrid metasurfaces that combine plasmonic metals with dielectrics provide access to both electric and magnetic effects, as well as their combination. This is especially useful when quantum emitters, such as fluorescent molecules, are combined with the metasurface. On the one side, the strong field enhancement provided by the plasmonic metal can be used to excite the molecule, while the dielectric resonator can prevent fluorescence quenching, limit absorption and enhance radiation. In this presentation, we review the design and fabrication of such metasurfaces and characterize experimentally their interaction with fluorescent molecules. We also show how a location-specific position of the emitters can control the overall optical response.

Olivier J.F. Martin studied physics at the Swiss Federal Institute of Technology Lausanne (EPFL) and conducted his PhD at IBM Zurich Research Laboratory, where he studied semiconductor lasers. After a stay at the UC San Diego, he became Assistant Professor at the Swiss Federal Institute of Technology Zurich (ETHZ). In 2003 he was appointed at the EPFL, where he is currently Full Professor of Nanophotonics and Optical Signal Processing. Dr. Martin conducts a comprehensive research that combines the development of numerical techniques for the solution of Maxwell’s equations with advanced nanofabrication and experiments on plasmonic systems. Applications of his research include optical antennas, metasurfaces, nonlinear optics, optical nano-manipulations, heterogeneous catalysis, security features and optical forces at the nanoscale. Dr. Martin has authored over 300 journal articles and holds several patents and invention disclosures.
