800G Ethernet specification

The 25 Gigabit Ethernet Consortium has decided to ditch its name as it heads off in search of serious speed with 800G specification. To mark the new name, the group has published 800G specification [PDF] that details its next step in Ethernet’s evolution. Ethernet standards group leaves its name in the dust as it details

Bidirectional optical device

Traditionally, an optical communication system would require two components at each end: transmitter and receiver. It has been known that LEDs can act as photo sensors, but they have not been very practical for optical communications applications. Researchers have now shown switching between LED and photodetector modes on new type component quickly enough for real-time

To Crack the Toughest Optimization Problems, Just Add Lasers – IEEE Spectrum

https://spectrum.ieee.org/computing/hardware/to-crack-the-toughest-optimization-problems-just-add-lasers Optimization is very important but is usually computationally very hard. Optimization encompasses far more than the traveling salesman problem. Scheduling is another difficult optimization challenge. Given the fact that the era of steady, large improvements in computer-processor performance appears to be coming to a close, researchers have begun to explore machines specially designed for

This 3D-printed AI construct analyzes by bending light | TechCrunch

https://techcrunch.com/2018/07/26/this-3d-printed-ai-construct-analyzes-by-bending-light/ Machine learning systems, which we frequently refer to as a form of artificial intelligence, at their heart are just a series of calculations made on a set of data. The calculations themselves aren’t particularly complex. Researchers from UCLA show that those calculations can be implemented optically with 3D-printed layers of transparent material, imprinted with

Physicist Have Created A New Form Of Light That Can Interact Like Atoms | IFLScience

http://www.iflscience.com/physics/physicist-have-created-a-new-form-of-light-that-can-interact-like-atoms/ American researchers have been able to create a three-photon bound state that represents a completely new form of light. As reported in Science, the researchers have been looking at complex interactions between photons for years. They obtained a two-photon state in 2013.
