Refractive index sensing with Fano resonant plasmonic nanostructures: a symmetry based nonlinear approach
Sensing using surface plasmon resonances is one of the most promising practical applications of plasmonic nanostructures and Fano resonances allow achieving a lower detection limit thanks to their narrow spectral features. However, a narrow spectral width ...
Royal Society of Chemistry2014A new strategy for improving fluorescent immunoassays using photonic crystals
Hans Peter Herzig, Elsie Barakat
The most widely used substrates for fluorescent immunoassay are based on transparent materials such as glass or plastic with almost no optical functionality. Very recently, optical nanostructures made of metal on dielectrics have been proposed to perform p ...
2014Large-scale sub-100 nm compound plasmonic grating arrays to control the interaction between localized and propagating plasmons
Olivier Martin, Thomas Gerd Siegfried, Arash Farhang
Compound plasmonic resonances arise due to the interaction between discrete and continuous metallic nanostructures. Such combined nanostructures provide a versatility and tunability beyond that of most other metallic nanostructures. In order to observe suc ...
Spie-Soc Photo-Optical Instrumentation Engineers2014Engineered Absorption Enhancement and Induced Transparency in Coupled Molecular and Plasmonic Resonator Systems
Hatice Altug, Shyamsunder Erramilli
Coupled plasmonic resonators have become the subject of significant research interest in recent years as they provide a route to dramatically enhanced light-matter interactions. Often, the design of these coupled mode systems draws intuition and inspiratio ...
2013Blue surface plasmon propagation along thin gold film-gas interface and its use for sensitive nitrogen dioxide detection
We demonstrate effective surface plasmon propagation along thin gold film in a blue spectral range: the measured 0.6 degrees angular width of the plasmon excitation peak corresponds to the propagation length around 7 mu m. For this end, we prepared a speci ...
Elsevier2013Fano Resonances in Plasmonic Nanostructures
Surface plasmons are able to generate extremely strong and confined optical fields at a deep-subwavelength scale, far beyond the diffraction limit, and now play a central role in nanosciences. A proper combination of plasmonic nanostructures can support Fa ...
EPFL2012Polariton lasing in a hybrid bulk ZnO microcavity
Nicolas Grandjean, Raphaël Butté, Jacques Levrat, Georg Rossbach
We demonstrate polariton lasing in a bulk ZnO planar microcavity under non-resonant optical pumping at a small negative detuning (delta similar to -1/6 the 130 meV vacuum Rabi splitting) and a temperature of 120 K. The strong coupling regime is maintained ...
2011Solving surface plasmon resonances and near field in metallic nanostructures: Green's matrix method and its applications
With the development of nanotechnology, many new optical phenomena in nanoscale have been demonstrated. Through the coupling of optical waves and collective oscillations of free electrons in metallic nanostructures, surface plasmon polaritons can be excite ...
2010Dynamics of Interactions of Confined Microcavity Polaritons
The present Ph.D. thesis consists in a series of experiments carried out in the Laboratory of Quantum Optoelectronics under the direction of professor Benoît Deveaud-Plédran between April 2006 and April 2010. We study the effect of lateral confinement on t ...
EPFL2010Plasmonic Nanofocusing in a Dielectric Wedge
We show that surface plasmon polaritons (SPPs) can be concentrated to subwavelength dimensions in a nanoscale dielectric wedge on a metal substrate. An adiabatic model explains how SPPs propagating on a Ag substrate covered with a thin Si film of slowly in ...
