Summary form only given. With modern nanofabrication techniques, surface plasmons can be engineered and controlled to yield unique optical properties which suggest many applications. This potential is well illustrated by the surface plasmon induced novel properties of subwavelength apertures.

Optics Letters, 2005
A new method for optically exciting and visualizing surface plasmons in thin metal films is described. The technique relies on the use of a high-numerical-aperture objective lens to locally launch a broad wavelength spectrum of surface waves and to detect the leaky radiative modes associated with them.

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.

Surface-plasmon optical techniques
Current Opinion in Colloid & Interface Science, 1999Abstract Over the past years, surface plasmons became a classical optical tool for the characterization of interfaces and thin films, e.g. for biosensor applications. And despite the fact that a number of commercial instruments are available we still see considerable effort in developing new schemes and formats aimed at improving the resolution and ...

SURFACE PLASMON DIFFRACTION BIOSENSOR
Journal of Nonlinear Optical Physics & Materials, 2005We describe experiments with surface plasmon polaritons excited by a laser beam in the Kretschmann configuration that are diffracted by a periodic pattern at the metal/dielectric interface. This suggested technique has become a novel sensing principle with particular potential for bio-affinity studies.

Surface plasmon subwavelength optics
Nature, 2003Surface plasmons are waves that propagate along the surface of a conductor. By altering the structure of a metal's surface, the properties of surface plasmons--in particular their interaction with light--can be tailored, which offers the potential for developing new types of photonic device. This could lead to miniaturized photonic circuits with length

Semiconductor Surface Plasmon Sources
Physical Review Letters, 2010Surface-plasmon polaritons (SPPs) are propagating electromagnetic modes bound at a metal-dielectric interface. We report on electrical generation of SPPs by reproducing the analogue in the near field of the slit-doublet experiment, in a device which includes all the building blocks required for a fully integrated plasmonic active source: an electrical ...

Surface Plasmon Interference Nanolithography
Nano Letters, 2005A new nanophotolithography technique based on the interference of surface plasmon waves is proposed and demonstrated by using computer simulations. The wavelengths of the surface plasmon waves at metal and dielectric interfaces can reach the nanometer scale while their frequencies remain in the optical range. As a result, the resolution of this surface

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.

Surface Plasmon Resonance Biosensing
2009Surface plasmon resonance (SPR) biosensors belong to label-free optical biosensing technologies. The SPR method is based on optical measurement of refractive index changes associated with the binding of analyte molecules in a sample to biorecognize molecules immobilized on the SPR sensor.
