Low-power optical device achieves around 100 times amplification using just a couple of hundred milliwatts of input power ...

Modern high-speed internet uses light to quickly and reliably transmit large amounts of data through fiber-optic cables, but currently, light signals hit a bottleneck when data processing is necessary ...

Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...

A new room-temperature quantum device developed at Stanford uses twisted light and advanced materials to link photons and ...

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.

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 ...

CU Boulder researchers have designed microscopic “racetracks” that trap and amplify light with exceptional efficiency. By using smooth curves inspired by highway engineering, they reduced energy loss ...

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 ...

Setup of the laser speckle contrast optical spectroscopy system used to monitor scalp and brain blood flow during temporary blockage of a major scalp artery near the temple. WASHINGTON, Oct. 21, 2025 ...

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 ...

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 ...
