The prototype, described as a nanostructured “active metamaterial,” was made from silver and an atomically thin semiconductor ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

PI (Physik Instrumente) announced a new technology platform for electro-optical wafer-level testing designed to validate ...

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.

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

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 ...

Currently, Kyocera’s technology enables aerial images whose focal positions vary by wavelength. In the future, increasing the ...

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 ...

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 ...

Scientists have created an optical device capable of mimicking black holes and the still hypothetical white holes. This system could revolutionize our understanding of the Universe and lead to ...
