Free electrons can efficiently absorb or emit plasmons excited in a thin conductor, giving rise
to multiple energy peaks in the transmitted electron spectra separated by multiples of the …

We present experimental observations of visible wavelength second-and third-harmonic
generation on single plasmonic nanowires of variable widths. We identify that near-infrared …

Surface polaritons display short wavelengths compared to propagating light, thus enabling
large spatial concentration and enhancement of electromagnetic energy. However, this …

Planar metamaterials represent a powerful paradigm of optical engineering, which enables
one to control the flow of light across structured material interfaces in the absence of high …

The proper choice of coating materials and methods in core–shell nanowire (NW)
engineering is crucial to assuring improved characteristics or even new functionalities of the …

The inorganic-organic hybrid perovskites are of great interest for potential applications in
high-performance optoelectronic devices, such as solar cells, lasers, and photodetectors …

Near-field imaging is a powerful tool to investigate the complex structure of light at the
nanoscale. Recent advances in near-field imaging have indicated the possibility for the …

In this study we present an analytical description of the ultrafast localized surface plasmon
and magnetic resonance dynamics in a single nanoparticle (Ag or Si), driven by an …

Plasmonic metal–insulator–metal tunnel junctions (MIM-TJs) readily excite surface plasmon
polaritons (SPPs) by inelastic electron tunneling, well below the diffraction limit, eliminating …

Next generation on-chip optical devices require light manipulation in time and space, that is,
control of group velocity of light in subwavelength dimensions. A waveguide in plasmonic …
