Researchers in Germany have unveiled an ultra-fast light switch made of very thin semiconductor ...

A new "lensless" device could help, as it uses light to instantly detect harmful microorganisms. Usually, in order to check drinking water for bacteria, a sample of that water must be cultured in a ...

Bill Gates is backing a bold bet that the next leap in computing power will not come from squeezing more transistors onto ...

Lithium niobate has emerged as a cornerstone material in advanced photonic technologies, owing to its exceptional electro‐optic coefficients, wide optical transparency and strong nonlinear properties.

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending spacetime, creating a point of no return. While black holes have fascinated ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different optical patterns at once is extremely complicated, and remains a major ...

It may seem at times that there is a divide between the optical/photonic domain and the RF one, with the terahertz zone between them as a demarcation. If you need to make a transition between the ...

(Nanowerk Spotlight) The human eye's remarkable ability to detect edges—the boundaries between light and dark areas in our visual field—is a fundamental aspect of how we perceive the world. This ...

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 from the Keck School of Medicine of USC and California Institute of Technology (Caltech) have developed a potential new way to measure a person's stroke risk that is ...

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending spacetime, creating a point of no return. While black holes have fascinated ...
