论文摘要
我们演示了含有纳米纤维部分的超低损失，全纤维Fabry-Pérot的腔体的制造，用于腔量子电动力学。通过在两个纤维bragg光栅之间制造纳米纤维期间，通过连续监测技巧和纤维半径，我们可以精确地评估锥度传播作为半径的函数。所得的空腔在纳米纤维腰部半径为207 nm的情况下，内部往返损失仅为0.31％，总往返半径为1380，最大预期的内部合作率为$ \ sim $ \ sim 1050 $ 1050 $ 1050纳米纤维表面上的纤维原子。我们制造如此高的纳米纤维腔的能力可能为实现高保真可伸缩的量子网络打开门。
We demonstrate the fabrication of ultra-low-loss, all-fiber Fabry-Pérot cavities containing a nanofiber section, optimized for cavity quantum electrodynamics. By continuously monitoring the finesse and fiber radius during fabrication of a nanofiber between two fiber Bragg gratings, we are able to precisely evaluate taper transmission as a function of radius. The resulting cavities have an internal round-trip loss of only 0.31% at a nanofiber waist radius of 207 nm, with a total finesse of 1380, and a maximum expected internal cooperativity of $\sim$ 1050 for a cesium atom on the nanofiber surface. Our ability to fabricate such high-finesse nanofiber cavities may open the door for the realization of high-fidelity scalable quantum networks.
