Surface Plasmons and Plasmonics
2020Surface plasmons (SPs) correspond to self-sustaining excitations of the electron gas of metals or semiconductors, i. e., to modulations of the density of such gas occurring at the surface of the body generating electric fields propagating along the surface and decaying exponentially perpendicular to it.

Graphene supports surface plasmons that have been observed to be both electrically and geometrically tunable in the mid- to far-infrared spectral regions. In particular, it has been demonstrated that graphene plasmons can be tuned across a wide spectral range spanning from the mid-infrared to the terahertz.

Color plasmons and trains of plasmons
Applied Optics, 2010We show that a broadband surface plasmon can be excited in a thin metal film. A train of two plasmons can be excited at conditions near the condition of broadband surface plasmon excitation. Also, a method for independent multichannel checks of biochips by wavelength addressing is proposed.

We study the ability of a plasmonic structure under illumination to release heat and induce fluid convection at the nanoscale. We first introduce the unified formalism associated with this multidisciplinary problem combining optics, thermodynamics, and hydrodynamics.

Plasmonic Nanopipette Biosensor
Analytical Chemistry, 2014Integrating a SERS immunoassay on a plasmonic "patch clamp" nanopipette enabled nanobiosensing for the detection of IgG. A SERS response was obtained using a sandwich assay benefiting from plasmon coupling between a capture Au nanoparticle (AuNP) on a nanotip and a second AuNP modified with a Raman active reporter and an antibody selective for IgG. The

(Invited) Graphene Plasmonics: Plasmon-Plasmon Hybridization and Chemical Sensing
ECS Meeting Abstracts, 2016Graphene has emerged as an interesting material for plasmonic applications in the terahertz to mid-infrared, the spectral region where its plasmonic resonance typically resides. The coupling behavior of graphene plasmons with both molecular vibrations and other plasmons will be presented.

Plasmonic Halos—Optical Surface Plasmon Drumhead Modes
Nano Letters, 2013We present the observation and systematic study of a novel optical phenomenon, a "plasmonic halo", wherein surface plasmons optically excited on circular silver microcavities form confined drumhead modes that, under resonant conditions, emanate colorful far-field radiation from their perimeter boundaries.

Focusing Surface Plasmons with a Plasmonic Lens
Nano Letters, 2005We report the focusing of surface plasmon polaritons by circular and elliptical structures milled into optically thick metallic films or plasmonic lenses. Both theoretical and experimental data for the electromagnetic nearfield is presented. The nearfield is mapped experimentally using nearfield scanning optical microscopy and plasmonic lithography. We
