By using paired, offset optical combs and RF electronics, researchers devised a unique atomic-clock architecture.

In defense and aerospace sectors, atomic clocks support advanced navigation systems, especially where satellite signals are ...

Abstract: This Special Issue of IEEE Journal on Emerging and Selected Topics in Circuits and Systems (JETCAS) is devoted to advancing the field of chip and package-scale communications across diverse ...

resonator for application in a new type of chip-scale atomic clock (CSAC). Near the half-hyperfine frequency of 133 Cs (4.596...GHz), the NTL oscillator provides a peak RF output power up to 14 dBm, ...

This issue of the Bulletin of the Atomic Scientists is devoted to lessons learned from the recent COVID pandemic—and how to stop or constrain the next pandemic, by buttressing public support for ...

“And it’s obvious where they will be forced to turn.” AI chip giant Nvidia has also publicly pushed back against the curbs. The tech executives called for more innovation and faster AI ...

This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...
