Enabling atom-clad waveguide operation in a microfabricated alkali vapor-photonic integrated circuit
Rahul Shrestha, Khoi Tuan Hoang, Peter Riley +5
Integrating alkali atomic vapors with nanophotonic devices offers a scalable route to quantum technologies that leverage strong atom-photon interactions. While there have been many…

Active compensation of the AC Stark shift in a two-photon rubidium optical frequency reference using power modulation
Yorick Andeweg, John Kitching, Matthew T. Hummon
We implement a feedback protocol to suppress the AC Stark shift in a two-photon rubidium optical frequency reference, reducing its sensitivity to optical power variations by a fact…

Sub-Doppler spectroscopy of the strontium intercombination line in a microfabricated vapor cell
Yang Li, John Kitching, Matthew T. Hummon
We report a 100 kHz linewidth for the 1S0 to 3P1 intercombination line of 88Sr atoms at 689nm in a microfabricated 9x14 x4.4 mm3 vapor cell. This puts an upper bound on the residua…
