Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...

This figure categorized into 2 primary categories: off-chip light source excitation and on-chip light source excitation, distinguished by their approaches to exciting electromagnetic field hotspots.

New research presents a strategy for observing and manipulating the optical Berry phase in Möbius ring microcavities. In their paper, the authors discuss how an optical Berry phase can be generated ...

The research group proposed and tested a nano-antenna that uses the specific optical resonance of dielectric nanoparticles to form a near field of circularly polarized light. This technique bolsters ...

Materials consisting of a few atomic layers display properties determined by quantum physics. In a stack of such layers, vibrations of the atoms can be triggered by infrared light. New experimental ...

Researchers in Germany and Australia have grown two-dimensional materials directly on optical fibres for the first time, creating a new hybrid platform with possible applications in a host of ...

A silicon-lithium niobate metasurface controls light through air at gigahertz speeds, advancing compact systems for optical communication and signal routing. (Nanowerk Spotlight) Optical systems that ...

Almost anytime physicists announce that they’ve discovered a new particle, whether it’s the Higgs boson or the recently bagged double-charm tetraquark, what they’ve actually spotted is a small bump ...
