总结了最近通过聚焦离子束铣削成预定单光子发射器的金刚石衬底来定义微观固体浸没透镜（SIL）的研究成果。我们展示了如何以至少100纳米的横向精度和500纳米的轴向精度确定单个发射器的位置，以及如何优化铣削过程。测量了金刚石中单发射极氮空位（NV）中心在SIL产生前后的特性，并进行了比较。[111]定向NV中心的计数率为1.0 x 10(6)次/秒。(C) 2014 AIP出版有限责任公司
Recent efforts to define microscopic solid-immersion-lenses (SIL) by focused ion beam milling into diamond substrates that are registered to a preselected single photon emitter are summarized. We show how we determine the position of a single emitter with at least 100 nm lateral and 500 nm axial accuracy, and how the milling procedure is optimized. The characteristics of a single emitter, a Nitrogen Vacancy (NV) center in diamond, are measured before and after producing the SIL and compared with each other. A count rate of 1.0 x 10(6) counts/s is achieved with a [111] oriented NV center. (C) 2014 AIP Publishing LLC.
