Physicists and chemists at Heidelberg University have realized a photonic microchip that is driven by light just as easily as ...

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 the dynamic realm of optical physics, researchers are continually pushing the boundaries of how light can be manipulated and harnessed for practical applications. As reported in Advanced Photonics ...

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.

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

A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing. A new generation of ...

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

Glass nanostructures etched using high-intensity femtosecond laser pulses promise to keep vast quantities of data safe for billions of years, describe Peter Kazansky, Ausra Cerkauskaite and Rokas ...

Modern-day communications rely on both fibre-optic cables and wireless radiofrequency (RF) microwave communications. Reaching higher data transmission capabilities is going to require technologies ...

Optical coherence tomography (OCT) is an imaging technology that can non-invasively generate cross-sectional images of tissue. OCT is widely used in eye clinics to diagnose and manage retinal diseases ...
