Integrating cavity quantum electrodynamics and ultracold-atom chips with on-chip dielectric mirrors and temperature stabilization

T. P. Purdy, D. M. Stamper-Kurn

摘要:

我们制作了一个原子芯片器件,它结合了冷原子磁捕获电路和适用于单原子强耦合腔QED的高精细度光学谐振腔。在横向尺寸< 100 μ m的微图案化片上平面镜和悬置在芯片上方的曲面镜之间形成精细度F > 2 × 10^5的法布里-珀罗光学谐振器。在原子芯片的模拟操作期间,利用片上电元件和光学元件之间的强且快速的热耦合来稳定伺服带宽超过100 kHz的腔镜分离。

英文摘要:

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-Perot optical resonators with finesse F > 2 X 10^5 were formed between a micropatterned on-chip planar mirror with lateral dimension of < 100 um 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.
