Abstract
Directional single-photon sources are of great interest for quantum communication and wireless optical nanocircuits. So far, directional nanoantennas are mostly fabricated by top-down approaches, typically expensive, time-consuming, non-scalable, and require state-of-the-art nanofabrication facilities. On the other hand, bottom-up approaches are relatively fast, inexpensive, and have great scalability. In particular, DNA origami method has been developed into a flexible, designable, and deterministic method for arranging plasmonic nanoparticles with molecular-level precision. These features make DNA origami an attractive method for the fabrication of directional optical nanoantennas. This work exploits DNA origami technology to construct single optical nanoantennas driven by single fluorescent molecules to obtain direction single-photon emission. The morphology and spatial arrangement of nanosized antenna elements are precisely controlled, and single quantum emitters are accurately attached to the hot spot of the antennas to provide local driving power in the optical frequency range. The presented method is a deterministic, precise, convenient, and cost-effective bottom-up fabrication method for mass production of the directional single-photon source.
