A single-photon source is an essential tool for the emerging field of quantum technologies. Ideally, it should be spectrally compatible with other photonic systems while providing a high flux of narrow-band photons. The single organic dye molecule dibenzanthantherene (DBATT) embedded into a n-tetradecane Spol'skii matrix under cryogenic conditions possesses the given characteristics, thus constitutes a prominent single-photon source. Nevertheless, the implementation of such a single-photon source requires an elaborate experimental setup involving a cryostat with a confocal microscope for the effective collection of the molecule's emission. Another approach is to use a single emitter coupled to an optical fiber. This approach has the potential to transfer a single-photon source from a proof-of-principle type of setup to a scalable "plug and play" device. Here we present the alignment-free fiber-coupled organic molecule single-photon source cooled down to cryogenic temperatures using a transport dewar as a cryostat. [ABSTRACT FROM AUTHOR]
