My Scientific Reports paper demonstrates a SABR-CPT microcell atomic clock driven by direct VCSEL current modulation and FPGA control, reaching range stability at one day (among the best reported performance for microcell-based CPT clocks). Notably, it is the first to reach this level without an external AOM or optical- and microwave-power stabilization servo loops.
I gave a talk at the Journées du Club Optique Microondes (JCOM 2025) in Toulouse, presenting my microwave microcell clock work and direct laser-current modulation approach.
I received a Best Student Paper Award at IFCS-EFTF 2025 for my microwave microcell atomic clock work, recognizing a compact pulsed CPT implementation based on direct laser-current modulation and FPGA control.
I gave an invited talk on my microwave microcell atomic clock work, presenting SABR-CPT interrogation with direct laser-current modulation and FPGA-based control at IFCS-EFTF 2025.
Our Applied Physics Letters paper reports a Cs microcell optical reference at 459 nm with stability at 1 s and at 200 s, using a simple saturated-absorption architecture and two quasi-identical systems for characterization.
I presented my latest results on advanced SABR-CPT interrogation using direct current modulation, including a custom FPGA-based atomic-signal tracking system for microwave microcell clocks.
At this INMAQS satellite workshop, I discussed the microwave microcell clock architecture and the direct laser-current modulation approach presented in my Ramsey-CPT work.
I presented my microwave atomic clock work at the European Frequency and Time Forum (EFTF 2024) in Neuchâtel, Switzerland.
Our Optics Letters paper reports sub-Doppler spectroscopy of the Cs transition at 459 nm, paving the way toward a microcell optical frequency reference with improved short-term stability.
My Applied Physics Letters article reports the first fully operational pulsed microwave microcell atomic clock using VCSEL current modulation and custom FPGA control, avoiding the need for an external optical shutter or acousto-optic modulator (AOM).
I started my PhD in the Time and Frequency department at FEMTO-ST, working on pulsed microwave atomic clocks and optical frequency references based on microfabricated vapor cells.
