A scanning probe-based pick-and-place procedure for assembly of integrated quantum optical hybrid devices
摘要:
集成量子光学混合器件包括基本组成部分,如单发射器和定制的光子纳米结构。可靠的制造方法需要在任意纳米结构上以最高精度控制活性纳米颗粒的沉积。在这里,我们描述了一种易于适应的技术,采用采摘和放置的纳米粒子与原子力显微镜结合共聚焦设置。以这种方式,可以在组装之前和之后同时监测形貌和光学响应。该技术可以应用于任意粒子。在这里,我们专注于纳米金刚石含有单氮空位中心,这是特别有趣的量子光学实验上的单光子和单发射水平。
英文摘要:
Integrated quantum optical hybrid devices consist of fundamental constituents such as single emitters and tailored photonic nanostructures. A reliable fabrication method requires the controlled deposition of active nanoparticles on arbitrary nanostructures with highest precision. Here, we describe an easily adaptable technique that employs picking and placing of nanoparticles with an atomic force microscope combined with a confocal setup. In this way, both the topography and the optical response can be monitored simultaneously before and after the assembly. The technique can be applied to arbitrary particles. Here, we focus on nanodiamonds containing single nitrogen vacancy centers, which are particularly interesting for quantum optical experiments on the single photon and single emitter level.
