Controlling light with light is a long-sought goal for computing and communication technologies. Achieving this capability ...

Researchers report building photonic computing chips that use light pulses to train spiking neural networks on ...

A tiny metasurface chip can turn invisible infrared light into steerable visible beams, opening the door to powerful new ...

Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter ...

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

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

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

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 ...

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 ...

By virtue of its $6.9 billion acquisition of Mellanox Technologies completed in early 2020, Nvidia became a seller of optical transceivers for Ethernet and InfiniBand, but seven years before that deal ...
