NIST researchers have developed compact chips that convert light into microwaves, potentially revolutionizing timing technology for various applications. The chips, about the size of a digital camera memory card, could improve GPS accuracy, phone and internet connections, radar systems, and more by reducing timing jitter to 15 femtoseconds.
The key innovation is shrinking the system from a tabletop size to a compact chip for the first time, reducing power usage and making the technology more practical for everyday devices. The ultimate goal is to integrate all components – lasers, modulators, detectors, and optical amplifiers – onto a single chip.
Precise timing is crucial for navigation systems, communication networks, and radar. The technology could enable more accurate GPS, better data transmission in communication networks, and improved radar sensitivity.
The research involved collaboration among multiple institutions, highlighting the importance of interdisciplinary collaboration in driving technological progress. The team aims to make all components work together effectively on a single integrated platform, reducing the need for extra technology and making it more accessible.
