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…

Wafer-scale fabrication of evacuated alkali vapor cells
Yang Li, Donggyu B. Sohn, Matthew Hummon +2
We describe a process for fabricating a wafer-scale array of alkali metal vapor cells with low residual gas pressure. We show that by etching long, thin channels between the cells…
