Electro-optical switch transmits data at record-low temperatures

A silicon optical switch newly developed at Sandia National Laboratories is the first to transmit up to 10 gigabits per second of data at temperatures just a few degrees above absolute zero. The device could enable data transmission ...

Frequency combs—on-chip integration on track

EPFL scientists have found a way to miniaturize frequency combs, realizing a new step toward miniaturization of such tools. Their device can measure light oscillations with a precision of 12 digits.

More efficient nano-LED opens door to faster microchips

The electronic data connections within and between microchips are increasingly becoming a bottleneck in the exponential growth of data traffic worldwide. Optical connections are the obvious successors but optical data transmission ...

Syncing data center computers at the speed of light

When several computers need to work together, as when calculating in parallel on several parts of a single large problem or managing a large database, they need to keep in step. These situations are particularly common in ...

Paving the way for fast low-energy data communications

Fibre-optic cables are revolutionising data communication worldwide. Within three years, Chalmers researchers expect to be able to transfer 100 Gb of data per second in a single fibre with one core, and several terabits per ...

Diamonds and quantum information processing on the nano scale

A City College of New York led-team headed by physicist Dr. Carlos Meriles has successfully demonstrated charge transport between Nitrogen-Vacancy color centers in diamond. The team developed a novel multi-color scanning ...

Ultracompact photodetector for optical data transmission

Data traffic is growing worldwide. Glass-fiber cables transmit information over long distances at the speed of light. Once they have reached their destination, however, these optical signals have to be converted into electrical ...
