By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...

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

Nvidia invested $4 billion in Lumentum, Coherent, and Ayar Labs to secure optical interconnect supply. The deals build competitive moats as AI clusters hit power limits.

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

Researchers have experimentally realized an optical effect predicted over 75 years ago: the Tellegen effect, where electric ...

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 ...

In this Physics World Focus on Optics & Photonics you’ll find an interview with the healthcare photonics lead at the UK’s Centre for Process Innovation, and a report on a pan-European effort to ...

Research shows that external impulses in non-reciprocal optical solitary waves can exceed expected momentum responses, ...
