Smaller than a coin, this optical device could enable rapid prototyping on the go. Researchers have demonstrated the first chip-based 3D printer, a tiny device that emits reconfigurable beams of visible light into a well of resin that rapidly cures into a solid shape. The advance could enable a 3D printer small enough to fit in the palm of a person’s hand.

Imagine a portable 3D printer you could hold in the palm of your hand...

A new semiconductor architecture integrates traditional electronics with photonic, or light, components could have application in advanced radar, satellites, wireless networks and 6G telecommunications. And it provides a pathway for a local semiconductor industry.

Researchers at the University of Sydney Nano Institute have invented a compact silicon semiconductor chip that integrates electronics with photonic, or light, components. The new technology significantly expands radio-frequency (RF) bandwidth and the ability to accurately control information flowing through the unit.

Expanded bandwidth means more information can flow through the chip and th...

The new photonic chip enables exponentially faster and more energy-efficient artificial intelligence. Scientists have developed a fast and extremely efficient method for transferring huge amounts of data. The technique uses dozens of frequencies of light to transfer several streams of information over a fiber optic cable simultaneously.

The data centers and high-performance computers that run artificial intelligence programs, such as large language models, aren’t limited by the sheer computational power of their individual nodes...

By merging two or more sources of light, interferometers create interference patterns that can provide remarkably detailed information about everything they illuminate, from a tiny flaw on a mirror, to the dispersion of pollutants in the atmosphere, to gravitational patterns in far reaches of the Universe.

“If you want to measure something w...
