We have fabricated an atom chip device which combines the circuitry for magnetic trapping of cold atoms with high-finesse optical resonators suitable for cavity QED in the single-atom strong coupling regime. Fabry–Pérot optical resonators with finesse \(\mathcal{F}\ge2\times10^5\) were formed between a micropatterned on-chip planar mirror with lateral dimension of ≤ 100 μm and a curved mirror suspended above the chip. The strong and rapid thermal coupling between on-chip electrical and optical elements was utilized to stabilize the cavity mirror separation with servo bandwidth exceeding 100 kHz during simulated operation of the atom chip.
