Abstract

The convergence of atomic spectroscopy, MEMS cell technologies and integrated photonics has led to the deployment of high-precision chip-scale atomic devices [1]. In this talk, we will present in-progress studies at FEMTO-ST Institute, France, for the development of microcellbased microwave and optical atomic clocks, with enhanced stability performances.<br&gtIn the first part, we will talk about the demonstration of CPT-based microwave cell clocks with stability at 1 day in the low 10−12 range [2], made possible thanks to the combination of advanced Ramsey-based interrogation sequences [3] and cells built with low gas permeation windows [4-5].<br&gtIn the second part, we will discuss the in-progress development of a microcell-based optical frequency reference based on the two-photon transition of Rb atom at 778 nm. An encouraging short-term stability of 3 × 10−13 at 1 s and 3 × 10−14 at 100 s has been recently achieved [6].<br&gtFuture studies will be briefly discussed.
