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 ...

Electrically pumped semiconductor lasers are among the most important sources owing to their high efficiency, compactness, and solid-state stability. For the mid-infrared and terahertz radiations, ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...

Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner ...

Scientists have beamed a laser into the sky, which was visible from miles around. The spectacle, known as The Beam, marked ...

(Nanowerk News) The light control performance of photonic crystals is closely related to their lattice constant, which typically requires the lattice constant to be in the same order of magnitude as ...

Important instruments for neuroscience and medical diagnostics, optically pumped magnetometers measure responses of polarized atoms to produce information about the low-frequency external field. They ...
