A high-level schematic of the photonic integrated chip, developed by the Gaeta lab, for all-optical optical frequency division, or OFD—a method of converting a high-frequency signal to a lower ...

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 ...

Vector modulation is increasingly used in microwave and satellite communication applications, but generating vector-modulated signals for measurement can be difficult and expensive. However, using ...

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 ...

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 ...

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 ...

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

The achievement provides a promising pathway towards small-footprint ultra-low-noise microwave generation for applications such as high-speed communication, atomic clocks, and autonomous vehicles. A ...
