The disappearance of sea ice in polar regions due to global warming not only increases the amount of light entering the ocean, but also changes its color. These changes have far-reaching consequences ...

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

It's not easy being green. Scientists for years have made small red and blue lasers, but other colors, including green, have been a challenge. A team has now filled this technology gap by creating ...

Over the past several decades, researchers have been making rapid progress in harnessing light to enable all sorts of scientific and industrial applications. From creating stupendously accurate clocks ...

Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner by RIKEN researchers. Such carbon nanotubes could form the basis of future ...

How dark is the night sky where you live? If you’re in an urban area, the answer will likely be “not dark at all”. The pervasiveness of artificial light – be it in the form of streetlamps, billboards, ...
