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 ...

The Global Timing Devices Market, valued at USD 5.92 billion in 2023, is projected to expand at a CAGR of 7.3%, reaching roughly USD 10.5 billion by 2033. Timing devices—oscillators, resonators, clock ...

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 ...

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 ...

The result is a clock with a total a total systematic uncertainty of 2.2×10⁻¹⁶ — a precision that means it loses less than a second every 140 million years. This extremely subtle lag is ...

Already, we’ve seen large-scale firings and rejections of research proposals. Recent guidance from the Office of Management and Budget shows the administration intends to assiduously follow the ...
