Plasmonic 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 ...

An RCWA Analysis of Solar Cell Back Reflectors: Comparison between Modelling and Experiment

Christophe Ballif, Hans Peter Herzig, Franz-Josef Haug, Toralf Scharf, Karin Söderström, Vincent Paeder, Ali Naqavi

We present a comparison between spectrally-resolved reflection measurements of gratings and theoretical predictions from RCWA approach. Diffraction intensities vary significantly with polarization, and surface plasmon absorption is observed around the onse ...

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 ...

Reusable Localized Surface Plasmon Sensors Based on Ultrastable Nanostructures

Noelia Laura Bocchio

Nanoparticle arrays created by nanosphere lithography are widely used in sensing applications since their localized surface plasmon resonances are extremely sensitive to changes in the local dielectric environment. A major drawback for any biologically ori ...

Narrowband optical interactions in a plasmonic nanoparticle chain coupled to a metallic film

Olivier Martin, Daniele Brunazzo

We study the coupling of localized surface plasmon (LSP) and surface-plasmon polariton (SPP) modes in a system composed of a metallic nanoparticle chain separated from a thin metallic film by a dielectric spacer. The thickness of such a spacer influences t ...

Optical Society of America2009

The propagation of surface plasmon polaritons guided along Au metal waveguides fabricated by electron-beam lithography is experimentally investigated using simultaneous near-field excitation and detection of plasmon-polariton modes localized at the air/Au ...

, ,

We present results of numerical simulations and preliminary experiments to investigate and characterize the effect of asymmetrical coupling of normally incident light to surface plasmon polaritons (SPPs) on metallic blazed gratings. Two types of blazed gra ...

Surface polaritons of small coated cylinders illuminated by normal incident TM and TE plane waves

Juan Ramon Mosig, Olivier Martin

The surface polariton properties of TM or TE plane wave scattered by a coated cylinder are investigated in this paper. The coated cylinder (whose outer radius is much smaller than the wavelength) is assumed to be electrically small and low dissipative. Ana ...

Surface plasmon propagation on thin metal films

Sergei Sidorenko

Surface plasmon-polaritons (SPPs) – electromagnetic waves propagating on the boundary between a metal and a dielectric and tightly bound to the interface – have been known for years. Recent progresses in microfabrication methods, near-field characterizatio ...

Optical interactions in a plasmonic particle coupled to a metallic film

Olivier Martin

The interplay between localized surface plasmon (LSP) and surface plasmon-polariton (SPP) is studied in detail in a system composed of a three-dimensional gold particle located at a short distance from a gold thin film. Important frequency shifts of the LS ...
