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 ...

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 ...

A team of researchers at the USC’s (University of Southern California) Ming Hsieh Department of Electrical and Computer Engineering has designed what it calls “the first optical device that follows ...
