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 ...

Light is not only an important carrier of information but also a carrier of energy. When light interacts with matter, it can induce subtle mechanical effects, known as optical forces. This non-contact ...

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 ...

A team of researchers led by Prof. SHAO Dingfu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Prof. XIAO Ruichun and Prof. LI Hui from Anhui ...

An Oxford researcher has found that transparent conducting electrodes can reduce perovskite–silicon tandem solar cell efficiency by over 2%, with losses linked to electrical resistance, optical ...

Researchers at the University of California, Los Angeles (UCLA) have developed an optical computing framework that performs large-scale nonlinear computations using linear materials. Subscribe to our ...

Add Yahoo as a preferred source to see more of our stories on Google. Not one, but two stunning optical effects were spotted overhead in Minnesota as the state was gripped by freezing temperatures.

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 ...
