Modern-day communications rely on both fibre-optic cables and wireless radiofrequency (RF) microwave communications. Reaching higher data transmission capabilities is going to require technologies ...

Microwave frequency combs offer a powerful platform for precision timing, sensing, and signal processing, but their practical use has long been ...

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 ...

Microwave frequency combs offer a powerful platform for precision timing, sensing, and signal processing, but their practical use has long been ...

Quantum technologies, which leverage quantum mechanical effects to process information, could outperform their classical counterparts in some complex and advanced tasks. The development and real-world ...

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 ...

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 ...

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, ...
