This is the reality for astronomers today, who are capturing faint signals that have traveled for over 13 billion years to reach Earth. These signals originate from a time when the universe was still ...

Scientists have detected ancient microwave signals from the universe's early days. These signals, over 13 billion years old, ...

Quantum physicists have found a way to make clouds of atomic-scale spins act like a single, disciplined antenna, generating microwave signals that are both powerful and remarkably long lived. Instead ...

Here’s the thing about radio signals. There is wild and interesting stuff just getting beamed around all over the place. Phrased another way, there are beautiful signals everywhere for those with ears ...

Optoelectronic oscillators (OEOs) represent a pivotal technology at the intersection of photonics and microwave engineering. By exploiting the long delay lines provided by optical fibres and high‐Q ...

The Photonics Research Group and IDlab, two imec research groups at Ghent University, and imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, have published ...

For the first time, scientists have used Earth-based telescopes to look back over 13 billion years to see how the first stars in the universe affect light emitted from the big bang. Using telescopes ...

How a single silicon chip was designed to be microwave and optical signal-processing engine. The various roles for which this engine can be reconfigured. The performance considerations that were ...

Scientists at UBC have devised a chip-based device that acts as a "universal translator" for quantum computers, converting delicate microwave signals to optical ones and back with minimal loss and ...
