Low temperature studies of molecules in solid state using an optical nanofiber — •Ariane Stiebeiner, Nils Konken, David Papencordt, Ruth Garcia-Fernandez, and Arno Rauschenbeutel — Technische Universität Wien - Atominstitut, Stadionallee 2, 1020 Wien, Austria

Molecules in solids have proven to be a versatile system for studying quantum optical effects and for realizing single photon sources. Coupling the emitters to optical nanofibers further enhances the potential of this system. The strong radial confinement and the pronounced evanescent field of the guided light in optical nanofibers yield a high excitation and emission collection efficiency [1, 2]. We present low temperature studies on terrylene doped p-terphenyl crystals on the nanofiber waist of a tapered optical fiber. The high sensitivity of our method should allow us to perform single molecule spectroscopy and to realize an all-fiber-based single photon source.
