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 ...

Artificial intelligence companies are spending billions on chips and infrastructure. Researchers think optical computing could help.

A schematic of a next-generation ultra-thin camera that utilizes metasurfaces, a nano-optical device, to secure light paths: By aligning metasurfaces horizontally on a glass substrate, light reflects ...

A key problem facing artificial intelligence (AI) development is the vast amount of energy the technology requires, with some ...

A new breakthrough in the field of physics led by doctoral student Yueming Yan could allow for the creation of small, thin, low-power optical devices to be used in both medical imaging and ...

Electrical signals control a vast number of activities in the human body, from exchanges of messages between brain neurons and stimulation of the heart muscle to the impulses that enable hands and ...

Historically, metasurface research has concentrated on the full manipulation of light's characteristics, resulting in a diverse array of optical devices such as metalenses, metaholograms, and beam ...

Microsoft has teamed up with Barclays on a novel approach to tackling artificial intelligence (AI) and optimisation problems based on a scalable analogue optical computer (AOC) architecture, designed ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

A panel of healthcare experts in the UK has urged makers of pulse oximeters to design “better, smarter” devices that are not biased by skin tone - possibly by developing multi-wavelength systems that ...
