An electrically-pumped single-photon source design with a predicted efficiency of 89% is proposed. The design is based on a quantum dot embedded in a photonic nanowire with tailored ends and optimized contact electrodes. Unlike cavity-based approaches, the photonic nanowire features broadband spontaneous emission control and an improved tolerance towards fabrication imperfections. The various builidng blocks of the design are analyzed using an elements-splitting approach.
