By repeatedly splitting the beams, changing their phase, and recombining them, they could make the light effectively carry out matrix multiplication. At the end of the chip, the researchers placed ...

Generally speaking, the more transistors a chip has, the more computing power it has — and the more power it requires to operate. You may like World's first light-powered neural processing units ...

have shown that light-based, or photonic, components “can do things that we care about, and that they can do them better than electronic chips that we already have,” says Anthony Rizzo ...

An optical fibre technology can help chips communicate with each other at the speed of light, enabling them to transmit 80 times as much information as they could using traditional electrical ...

Training at the speed of light To test the chip's potential, the team used the chip to solve benchmark AI problems. The platform achieved over 97% accuracy on a simple nonlinear decision boundary ...

University of Pennsylvania engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to ...

To improve photonic and electronic circuitry used in semiconductor chips and fiber optic systems, researchers at the McKelvey ...

A new type of computer that uses light rather than electricity could perform calculations faster, using less energy and less space. Computer chips are made up of millions or billions of logic gates.

Instead of using a different laser to generate each wavelength of light, the new chips require only a single laser to generate hundreds of distinct wavelengths of light that can simultaneously ...

Focusing light is important for various technological applications on photonic chips, such as quantum communication, optical sensors, and on-chip lasers. "Until now, we knew two general strategies ...
