Aero-optical effects arise when variations in the refractive index—prompted by turbulence, temperature gradients and pressure fluctuations within high-speed airflow—distort the transmission of light.

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 ...

A San Francisco photographer captured a stunning optical display behind the Transamerica Pyramid Thursday amid an unusual ...

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 ...

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 ...

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 ...
