A novel technique for enhancing optical spring that utilizes the Kerr effect to improve the sensitivity of gravitational wave detectors (GWDs) has recently been developed. This innovative design uses ...

The Goos-Hänchen effect refers to the small lateral displacement experienced by a light beam when it is reflected from an interface, a phenomenon that deviates from the simple predictions of geometric ...

A tiny optical device built into a silicon chip has achieved the slowest light propagation on a chip to date, reducing the speed of light by a factor of 1,200 in a study reported in Nature Photonics ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

What are Tunable Optical Materials? Tunable optical materials are a class of nanomaterials that can manipulate light in a controllable and dynamic manner. These materials have optical properties, such ...

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 ...

Researchers have experimentally realized an optical effect predicted over 75 years ago: the Tellegen effect, where electric ...
