Integrated optical interfaces for quantum emitters are a prerequisite for implementing quantum networks. In this context, tapered optical fibers with a nanofiber waist recently received significant attention as an efficient means of light-matter interaction. Due to the sub-wavelength diameter of the waist, a large fraction of the light propagates outside of the fiber as a high-intensity evanescent wave. An emitter brought close to the surface of the nanofiber has a large effect on the guided light field. Here, we couple single organic dye molecules to the guided modes of an optical nanofiber. The molecules are embedded in a nano-crystal host that provides photostability and due to the resulting inhomogeneous broadening, a means to spectrally address single molecules. The molecules are optically excited and their fluorescence is detected solely via the nanofiber interface without the requirement of additional optical access. In this way, we realize a fully fiber-integrated system that is scalable and may become a versatile constituent for quantum hybrid systems.
