An international team of researchers has developed a novel technique to efficiently excite and control highly-confined ...

Plasmons, which may be thought of as clouds of electrons that oscillate within a metal nanocluster, could serve as antennae to absorb sunlight more efficiently than semiconductors. Understanding and ...

Surface plasmons are collective oscillations of free electrons that occur at the interface between a metal and a dielectric medium, such as air or glass. These oscillations are coupled with ...

Photonic computing, storage, and communication are the foundation for future photonic chips and all-optical neural networks. Nanoscale plasmons, with their ultrafast response speed and ultrasmall mode ...

Recently, we demonstrated an all-optical coupling scheme for plasmons, which takes advantage of the intrinsic nonlinear optical response of graphene. Frequency mixing using free-space, visible light ...

TOKYO — July 22, 2024 — NTT Corporation and The University of Tokyo announced they have generated and controlled graphene plasmon wave packets with a pulse width of 1.2 picoseconds. They said this ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is predicted to account for most of the universe's mass. As it cannot be detected and studied using ...

TEMPE, Ariz.--(BUSINESS WIRE)--Biosensing Instrument Inc (BI) introduces today SPRm 220, a new cell-based surface plasmon resonance (SPR) system. Building on the award-winning SPR microscopy ...

In recent years, advances in photonics and materials science have led to remarkable developments in sensor technology, pushing the boundaries of what can be detected and measured. Among these ...
