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

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 ...

Researchers report a room-temperature organic microcavity where two different forms of spin–orbit coupling act together to ...

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 ...

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 ...

The detection of gravitational waves stands as one of the most significant achievements in modern physics. In 2017, gravitational waves from the merger of a binary neutron star were detected for the ...
