The discovery of the enhancement of Raman scattering by molecules adsorbed on
nanostructured metal surfaces is a landmark in the history of spectroscopic and analytical …

Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic
nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of …

Active plasmonics is a burgeoning and challenging subfield of plasmonics. It exploits the
active control of surface plasmon resonance. In this review, a first-ever in-depth description …

The vast development of nanofabrication has spurred recent progress for the manipulation
of light down to a region much smaller than the wavelength. Metallic plasmonic array …

Metamaterials are typically engineered by arranging a set of small scatterers or apertures in
a regular array throughout a region of space, thus obtaining some desirable bulk …

Light scattering by small particles has a long and interesting history in physics. Nonetheless,
it continues to surprise with new insights and applications. This includes new discoveries …

The unprecedented ability of nanometallic (that is, plasmonic) structures to concentrate light
into deep-subwavelength volumes has propelled their use in a vast array of nanophotonics …

Amplifiers and lasers based on surface plasmon–polaritons (SPPs) have been studied for
around three decades. Research in this area has experienced particularly significant growth …

Plasmonics is a revolutionary concept in nanophotonics that combines the properties of both
photonics and electronics by confining light energy to a nanometer-scale oscillating field of …

Optical microresonators 1, which confine light within a small cavity, are widely exploited for
various applications ranging from the realization of lasers 2 and nonlinear devices 3, 4, 5 to …
