实验证明了纳米级发射器的基于光纤的双向光子检测以及两个单模光纤 (SMF) 的两个输出之间的光子反聚束行为。含有外延生长的量子点 (QD) 的薄片通过 SMF 跳线的边缘面机械固定在两侧。单个量子点发射的光子通过 SMF 直接从两侧取出。通过检测二阶光子相关测量中的非经典反聚束，可以确认两个 SMF 输出之间的单光子发射。这种简单的光机械免对准单光子发射器具有超过三个月的强大稳定性和低成本制造的优势。
Fiber-based bidirectional photon detection from nanoscale emitters and photon antibunching behavior between two outputs of two single-mode fibers (SMFs) are experimentally demonstrated. Flakes containing the epitaxially grown quantum dots (QDs) are mechanically fixed by both sides with the edge faces of the SMF patch cables. The emitting photons from a single QD are directly taken out of both sides through the SMFs. Single-photon emission between two SMF outputs is confirmed by detecting nonclassical antibunching in second-order photon correlation measurements. This simple optomechanical alignment-free single-photon emitter is advantageous because of its robust stability of more than three months and low-cost fabrication.
