Book excerpt: We describe chip-scale batch-fabricated cesium cells utilizing semiconductor wafer processing, pin transfer of cesium, and silicon/Pyrex anodic bonding for cell sealing. Highspeed, single-mode linearly polarized VCSELs emitting at the 133Cs D1 line were fabricated, optimized for low threshold and high-speed operation with overall small power dissipation. Coherent population trapping (CPT) end-resonance signals with a contrast and linewidth of 5.4% and 7.1 kHz respectively are achieved using 1 mm optical path length cells and VCSEL driven with 1.25 mW RF modulation and 2.76 mW DC power dissipation. We demonstrate short-term stability with an atomic clock built with these components operating on the CPT end-resonance. The magnetic field is stabilized with a novel magnetic field locking scheme tapping the Zeeman resonance.
