A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At ...

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

Narrow Main Beam, Low Side Lobes! High-Performance Electro-Optic Beam Steering with Thin-Film Lithium Niobate Optical ...

CU Boulder researchers have designed microscopic “racetracks” that trap and amplify light with exceptional efficiency. By using smooth curves inspired by highway engineering, they reduced energy loss ...

Industry analysis indicates that the market is moving decisively beyond simple LED replacement fixtures toward integrated, smart-ready lighting systems. The core challenge for optical manufacturers is ...

A nanophotonic diffractive network performs morphological image processing, including dilation and erosion, purely through light propagation.

Of the many feats achieved by artificial intelligence (AI), the ability to process images quickly and accurately has had an ...

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 ...
