A new atom camera uses one ultracold rubidium atom to map light intensity and polarization with spatial resolution below 100 nanometers.

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 ...

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 ...

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 ...

A research group led by Assistant Professor Takafumi Tomita and Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed a new microscopy ...

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 ...

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 ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

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 ...
