Adhering and coupling emitter-doped organic crystals to optical nanofibers — •David Papencordt, Ariane Stiebeiner, Nils Konken, Ruth Garcia-Fernandez, and Arno Rauschenbeutel — Technische Universität Wien - Atominstitut, Stadionallee 2, 1020 Wien, Austria

Optical nanofibers have proven to be an extremly sensitive tool for spectroscopy of particles near or on the fiber surface [1, 2]. Here, we present our results on adhering emitter-doped organic crystals to the nanofiber waist of a tapered optical fiber. The emitted fluorescence light is coupled into the guided mode of the fiber, allowing us to spectroscopically study crystal growth and guest-host interactions in the crystals. Additional information can be obtained by performing such measurements under cryogenic conditions. In particular, it should be possible to realize nanofiber-based spectrosopy at the single molecule level.
