Within this proposed project we would like to realize a novel system for controlled experiments in cavity quantum electrodynamics (CQED).We intend to use a toroidal microresonator as cavity and single defect centers in nano diamonds as quantum emitters. In order to realize a well controllable configuration we will use scanning probe techniques to position individual nano diamonds within the maximum field of whispering-gallery modes supported by the toroid. Light is coupled in and out of individual modes with the use of a tapered fiber coupler with high efficiency, and confocal excitation of individual nano diamonds is used. Temperature tuning of the cavity and DC Stark tuning of the defect centers will be implemented. We will investigate the weak as well as the strong coupling regime of CQED. For the first time we aim at controlled assembly of a CQED system with two quantum emitters.

在这个项目中，我们希望实现一个新的系统，用于腔量子电动力学（CQED）的控制实验。我们打算使用环形微谐振器作为腔和纳米金刚石中的单缺陷中心作为量子发射器。为了实现一个良好的可控配置，我们将使用扫描探针技术，以定位单个纳米金刚石的最大领域内的回音壁模式所支持的环形。光耦合进和出的各个模式与锥形光纤耦合器的使用具有高效率，并使用单独的纳米金刚石的共焦激发。将实现腔的温度调谐和缺陷中心的DC斯塔克调谐。我们将研究CQED的弱耦合和强耦合机制。第一次，我们的目标是控制组装的CQED系统与两个量子发射器。
