A single-photon source is an essential tool for the emerging field of quantum technologies. Ideally, it should be spectrally compatible with other photonic devices while providing a high flux of narrow-band photons. A single organic dye molecule dibenzanthanthrene (DBATT, C30H16) embedded into a n-tetradecane Spol’skiĭ matrix under cryogenic conditions possesses the given characteristics, hence constitutes a prominent single-photon source. Nevertheless, the implementation of such a single-photon source requires a complex experimental setup involving a cryostat with a confocal microscope for the effective collection of the molecular emission. Another approach is to use a single emitter coupled directly to the end facet of an optical fiber. This approach has the potential to transfer a single-photon source based on a quantum emitter from a proof-of-principle type of setup to a scalable “plug-and-play” device. Here we present a successful coupling of a single organic molecule to an optical fiber [1].
