Interfacing single molecules with optical nanofibers — •Hardy Schauffert, Sarah Skoff, David Papencordt, and Arno Rauschenbeutel — Technische Universität Wien, Atominstitut, Stadionallee 2 , 1020 Wien

In recent years, tapered optical fibers with nanowaist have gained a lot of attention as versatile platforms for strong light-matter interaction due to their small effective mode volume. The sub-wavelength diameter of the waist results in a crucial amount of light propagating outside of the fiber as a high intensity evanescent wave. An emitter brought close to the surface of the nanofiber can then have a big effect on the guided light field. Possible emitters are single organic molecule embedded in a crystal matrix such as terrylene in p-terphenyl. These molecules exhibit a naturally strong Zero-phonon-line, which can be as narrow as tens of MHz at cryogenic temperature and are very photostable. This together with optical nanofiber makes them promising candidates as building blocks for fiber integrated quantum networks. We will show first results on single molecule spectroscopy using optical nanofibers and give an outlook of the rich variety of experiments that can be done with such a platform.
