For nanowire-based sources of non-classical light, the rate at which photons are generated and the ability to efficiently collect them are determined by the nanowire geometry. Using selective-area vapour-liquid-solid epitaxy, we show how it is possible to control the nanowire geometry and tailor it to optimise device performance. High efficiency single photon generation with negligible multi-photon emission is demonstrated using a quantum dot embedded in a nanowire having a geometry tailored to optimise both collection efficiency and emission rate.
对于基于纳米线的非经典光源，光子产生的速率以及有效收集光子的能力由纳米线的几何结构决定。通过选择性区域气-液-固外延，我们展示了如何控制纳米线的几何结构并对其进行定制以优化器件性能。利用嵌入在具有经过定制以优化收集效率和发射速率的几何结构的纳米线中的量子点，展示了具有可忽略不计的多光子发射的高效单光子产生。
