Phase-continuous comparison of three all-optical time scales over 20 days
Dahyeon Lee, Kyungtae Kim, Zoey Z. Hu +11
Optical frequency standards have progressed rapidly over the past two decades, leading to the anticipated redefinition of the SI second by an optical frequency. However, time scale…
Universal zero-crosstalk photonic integration via slab-engineered mode hybridization
Kyungtae Kim, Yoseph Shin, Seungyong Lee +8
Photonic integrated circuits have emerged as a scalable platform for optical computing, communication, and quantum technologies, where high-fidelity optical processing is essential…
Atomic clock frequency ratios with fractional uncertainty
Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24
We report high-precision frequency ratio measurements between optical atomic clocks based on Al, Yb, and Sr. With total fractional uncertainties at or bel…
Frequency stability of in a Si cavity with AlGaAs crystalline mirrors
Dahyeon Lee, Zoey Z. Hu, Ben Lewis +8
