Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

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

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

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 its simplest form, a microresonator is a tiny device that can trap light and ...

A single layer of atoms may seem too thin to meaningfully interact with light, yet materials like tungsten disulfide are reshaping what is possible in nanophotonics. Researchers have now found a way ...

Photonics is gaining momentum as a platform for high-speed AI computing. Researchers in Singapore have demonstrated a passive, ultrafast, and integration-ready all-optical nonlinear activation ...

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 ...

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly ...

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 ...
