Atomic clock performance beyond the geodetic limit
W. F. McGrew, X. Zhang, R. J. Fasano +9
The passage of time is tracked by counting oscillations of a frequency reference, such as Earth's revolutions or swings of a pendulum. By referencing atomic transitions, frequency…

Ultra-stable optical clock with two cold-atom ensembles
M. Schioppo, R. C. Brown, W. F. McGrew +10
Atomic clocks based on optical transitions are the most stable, and therefore precise, timekeepers available. These clocks operate by alternating intervals of atomic interrogation…

Digital-photonic synthesis of ultra-low noise tunable signals from RF to 100 GHz
T. M. Fortier, A. Rolland, F. Quinlan +9
The demand for higher data rates and better synchronization in communication and navigation systems necessitates the development of new wideband and tunable sources with noise perf…
