Plasmon-exciton coupling
This journal describes its scope as focusing on “the interaction of photons with nano-structures”, a definition of nanophotonics that we believe most researchers in the field would agree with. Fundamental research in nanophotonics thus primarily involves …
Preparation and properties of plasmonic-excitonic nanoparticle assemblies
The assembly of inorganic nanoparticles often leads to collective properties that are different from the combined properties of the individual components. In particular, coupling plasmonic and excitonic nanoparticles has been shown to modify their optical …
High optical magnetism of dodecahedral plasmonic meta-atoms
The generation in artificial composites of a magnetic response to light, comparable in magnitude with the natural electric response, may offer an invaluable control parameter for a fine steering of light at the nanoscale. In many experimental realizations, …
Quantum dot plasmonics: from weak to strong coupling
The complementary optical properties of surface plasmon excitations of metal nanostructures and long-lived excitations of semiconductor quantum dots (QDs) make them excellent candidates for studies of optical coupling at the nanoscale level. Plasmonic devices …
Enhancing functionalities of atomically thin semiconductors with plasmonic nanostructures
Atomically thin, two-dimensional, transition-metal dichalcogenide (TMD) monolayers have recently emerged as a versatile platform for optoelectronics. Their appeal stems from a tunable direct bandgap in the visible and near-infrared regions, the ability to …
Six-fold plasmonic enhancement of thermal scavenging via CsPbBr3 anti-Stokes photoluminescence
One-photon up-conversion, also called anti-Stokes photoluminescence (ASPL), is the process whereby photoexcited carriers scavenge thermal energy and are promoted into a higher energy excited state before emitting a photon of greater energy than initially …
Phase-matched nonlinear second-harmonic generation in plasmonic metasurfaces
The phase matching between the propagating fundamental and nonlinearly generated waves plays an important role in the efficiency of the nonlinear frequency conversion in macroscopic crystals. However, in nanoscale samples, such as nanoplasmonic structures, …
Prospects and applications of plasmon-exciton interactions in the near-field regime
Plasmonics is a rapidly developing field at the boundary of fundamental sciences and device engineering, which exploits the ability of metal nanostructures to concentrate electromagnetic radiation. The principal challenge lies in achieving an efficient …
Pliable polaritons: Wannier exciton-plasmon coupling in metal-semiconductor structures
Plasmonic structures are known to support the modes with sub-wavelength volumes in which the field/matter interactions are greatly enhanced. Coupling between the molecular excitations and plasmons leading to the formation of “plexcitons” has been …
Polaritonics: from microcavities to sub-wavelength confinement
Following the initial success of cavity quantum electrodynamics in atomic systems, strong coupling between light and matter excitations is now achieved in several solid-state set-ups. In those systems, the possibility to engineer quantum emitters and …
