Next-generation atomic clock successfully tested at sea

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, communications and scientific ...

A layered approach sharpens brain signals in optical imaging

Near-infrared spectroscopy, or fNIRS, offers a way to monitor brain activity without surgery or radiation by tracking changes in blood flow and oxygenation. Light sources placed on the scalp send near-infrared light into ...

A tiny detector for microwave photons could advance quantum tech

Detecting a single particle of light is hard; detecting a single microwave photon is even harder. Microwave photons, the tiny packets of electromagnetic radiation used in current technologies like Wi-Fi and radar, carry far ...

Compact flat-lens system can generate nondiffracting bottle beams

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long distances. To overcome this challenge, ...
