Computer modeling is assisting the design of optical modulators with low losses to improve optical communications. "Our device has a speed and optical losses comparable to existing technology such ...

At the heart of this new computer is an optical implementation of a recurrent neural network. The device operates entirely within the optical domain, utilizing laser pulses to process data.

Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.

On the third floor of the University of Delaware’s Du Pont Hall, electrical engineers analyze delicate, centimeter-sized computer chips on a large optical table surrounded by oscilloscopes, lenses and ...

IBM scientists on Wednesday announced the development of a device that uses light, instead of copper wires, to allow computer chips to communicate. Written by Andrew Nusca, Contributor March 3 ...

Their simulations revealed that second-harmonic generation—a cornerstone of optical technologies like lasers and sensors—can occur at field intensities 1,000 to 10,000 times lower than those ...

Researchers at Washington University in St Louis have developed a new optical diode for computers that would run on light. Researchers claim that the component will make more powerful computers ...

The device makes voltage output even when dust is not being detected. This is because light emitted from the LED reflects at case of the device and some part of it gets to the detector. The output ...

While classical computers store and process information as “bits” that can have one of two states – “0” or “1” – a quantum computer exploits the ability of quantum particles to be in “superposition” ...
