To unlock materials of the future, including better photocatalysts or light-switchable superconductors, researchers need to ...

Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...

Inside most photonic chips, light races through tiny optical wires. It carries information far faster than electricity can in many conventional systems.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device that can dynamically control the "handedness" of light as it passes ...

A new optical microresonator chip keeps light circulating longer, enhancing efficiency for next-generation sensors and ...

Low-power optical device achieves around 100 times amplification using just a couple of hundred milliwatts of input power ...

A tiny optical device built into a silicon chip has achieved the slowest light propagation on a chip to date, reducing the speed of light by a factor of 1,200 in a study reported in Nature Photonics ...

The role of light in our lives is both pervasive and primordial. Ultraviolet light probably had a role in the very origins of life, and light-driven photosynthesis underlies all but the most primitive ...

Astrolight CEO Laurynas Mačiulis explains how laser satellite communication could ease spectrum congestion, increase data capacity, and raise new engineering and policy questions for space ...
