Study shows that if autonomous vehicles are widely adopted, hardware efficiency will need to advance rapidly to keep computing-related emissions in check.

Researchers have demonstrated directional photon emission, the first step toward extensible quantum interconnects.

A new method can produce a hundredfold increase in light emissions from a type of electron-photon coupling, which is key to electron microscopes and other technologies.

Researchers develop a scalable fabrication technique to produce ultrathin, lightweight solar cells that can be seamlessly added to any surface.

New technique could diminish errors that hamper the performance of super-fast analog optical neural networks.

Researchers have developed a programmable optical device for high-speed beam steering.

Researchers develop a technique for precisely arranging nanoscale particles on a surface, such as a silicon chip, that doesn’t damage the material.

A new method uses optics to accelerate machine-learning computations on smart speakers and other low-power connected devices.

The device senses and wirelessly transmits signals related to pulse, sweat, and ultraviolet exposure, without bulky chips or batteries.

Methods that make a machine-learning model’s predictions more accurate overall can reduce accuracy for underrepresented subgroups. A new approach can help.
