 abstract = {We report on the detection of high-contrast and narrow Coherent Population Trapping (CPT) Ramsey fringes in a Cs vapor cell using a simple-architecture laser system. The latter allows the combination of push-pull optical pumping (PPOP) and a temporal Ramsey-like pulsed interrogation. An originality of the optics package is the use of a single Mach-Zehnder electro-optic modulator (MZ EOM) both for optical sidebands generation and light switch for pulsed interaction. Typical Ramsey fringes with a linewidth of 166 Hz and a contrast of 33 \% are detected in a cm-scale buffer-gas filled Cs vapor cell. This technique could be interesting for the development of high-performance and low power consumption compact vapor cell clocks based on CPT.},

 abstract = {The combination of MEMS fabrication with atomic clocks has enabled a new generation of small, cheap, low-power devices. Since the proposal of chip-scale atomic clocks (CSACs) in 2002, the fields of MEMS-based atomic sensors and coherent population trapping (CPT) spectroscopy have progressed rapidly. This review gives an overview over microfabrication techniques used for CSACs, the fabrication and integration of the critical components. Furthermore, the performance of MEMS clocks is evaluated in terms of frequency stability and sensitivity to external parameters, size, and power consumption. Possibilities for reaching the final goal of a MEMS clock with a fractional frequency instability below 10-11 at 1 hour of integration in a package of volume of 1 cm3, consuming 30 mW of power, are discussed. Finally, a broad field of advances spectroscopic techniques is reviewed and their advantages and drawbacks for the improvement of chip-scale atomic clocks.},
