Description: All-optical, cavity-free microwave atomic clock based on coherent population trapping in an alkali vapor microcell, engineered for chip-scale size, weight and power.
Boudot has been a permanent CNRS researcher in the Time-Frequency department of FEMTO-ST since 2008, developing compact and miniaturized atomic clocks based on coherent population trapping (CPT) in cesium vapor microcells, including all-optical, cavity-free designs that remove the traditional microwave cavity to shrink clock volume toward chip scale for GNSS, telecom and potential deep-sea seismic-sensing deployment. He received the EFTF Young Scientist Award in 2020 for this work.
Hollberg works on optical atomic clocks, laser frequency stabilization, and frequency-comb metrology, including chip-scale and field-deployable clock technology with applications to relativistic geodesy and precision tests of fundamental physics.
