Researchers used the Poisson spot effect to create stable optical skyrmions with a laser and disc, simplifying studies for ...

A combined team of engineers from Jiangsu University and Harvard University used a non-destructive, light diffraction fingerprint technique to detect viral infections in cells. Their paper is ...

Coherent diffraction imaging (CDI) provides lens-free imaging with diffraction-limited resolution and has become an important imaging modality at synchrotron facilities worldwide. The performance of ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

During the recent decades, nonlinear optical properties of various atomic 1,2,3,4 and other coherent media 5,6 have been well studied due to quantum interference and coherence. As examples and owning ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

In recent years, the rapid growth of artificial intelligence and the Internet of Things (IoT) has driven a surge in computational demand. Traditional electronic computing, however, is approaching its ...

Did you have the same question as I did when you looked at the spectacular first light images from the $10 billion James Webb Space Telescope (JWST or “Webb” for short)? Yes, they are all incredible, ...

Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating. A diffraction grating is a kind of optical component whose ...

Sunlight reaches the earth as white light, which is made up of all the rainbow colors. Rainbow colors are red, orange, yellow, green, blue, indigo, and violet. It is easy to remember them by using the ...
