We propose and analyze three electrically-pumped nanowire single-photon source structures, which achieve output efficiencies of more than 80%. These structures are based on a quantum dot embedded in a photonic nanowire with carefully tailored ends and optimized contact electrodes. Contrary to conventional cavity-based sources, this non-resonant approach provides broadband spontaneous emission control and features an improved fabrication tolerance towards surface roughness and imperfections. Using an element-splitting approach, we analyze the various building blocks of the designs with respect to realistic variations of the experimental fabrication parameters.
我们提出并分析了三种电泵浦纳米线单光子源结构，其输出效率超过80%。这些结构基于嵌入光子纳米线中的量子点，该纳米线具有精心定制的端部和优化的接触电极。与传统的基于腔的光源不同，这种非共振方法提供宽带自发发射控制，并且对表面粗糙度和缺陷具有更高的制造容忍度。我们使用元件拆分方法，针对实验制造参数的实际变化分析了设计中的各个组成部分。
