Experimental verification of ‘waveguide’ plasmonics

New Journal of Physics, 2017
Surface plasmons polaritons are collective excitations of an electron gas that occur at an interface between negative- ε and positive- ε media. Here, we report the experimental observation of such surface waves using simple waveguide metamaterials filled

Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

Advanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

Coupling of a quantum emitter to the surface plasmons of a nanowire

, 2014
A finite element method is applied to study the coupling of a single photon emitter in nanodiamond to surface plasmons of a silver nanowire. Sensitivity of this system to different parameters is explored.

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

Advanced Materials Interfaces, EarlyView.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.

From weak to strong coupling of localized surface plasmons to guided modes in a luminescent slab [PDF]

, 2014
We investigate a periodic array of aluminum nanoantennas embedded in a light-emitting slab waveguide. By varying the waveguide thickness, we demonstrate the transition from weak to strong coupling between localized surface plasmons in the nanoantennas ...

Surface plasmons in terahertz metamaterials

Optics Express, 2008
We characterize terahertz metamaterials by applying apertureless near-field microscopy with a bandwidth that covers the entire spectral response of the structures. The observations agree with the interpretation of the fundamental mode of the metamaterial. But the high frequency resonance shows properties that deviate from the common interpretation.
