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.

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

Interaction between surface plasmons and localized plasmons
Physical Review B, 1985A theoretical analysis of the experiments of Holland and Hall [Phys. Rev. B 27, 7765 (1983)] is given. The metal-island film is characterized by an effective anisotropic dielectric function. Formulas for reflection and transmission coefficients for an anisotropic layered structure are given.

Surface-plasmon dispersion and multipole surface plasmons in Al(111)
Physical Review B, 2000We have measured the collective electronic excitations of the Al(111) surface by means of angle-resolved high-resolution electron-energy-loss spectroscopy. Loss spectra reveal both the monopole and the multipole surface plasmons. The measured dispersion of the monopole surface plasmon is negative, as predicted by calculations of the dynamic response of
