Single molecules evanescently coupled to optical nanofibers — •Sarah Margaretha Skoff, Hardy Schauffert, David Papencordt, and Arno Rauschenbeutel — Institute of Atomic and Subatomic Physics, Vienna University of Technology, Stadionallee 2, 1020 Vienna, Austria

In recent years, single molecules in solids have gained increased interest as building blocks for quantum networks, quantum metrology and nanosensors. For all these applications strong light-matter interactions are essential.

A versatile tool to achieve such interactions is an optical nanofiber, which is the tapered part of a commercial optical fiber that has a subwavelength diameter waist. This allows an appreciable amount of light to propagate outside the fiber in the form of an evanescent waist. Due to the strong transverse confinement of the light field which prevails over the entire length of the nanofiber, the interaction with emitters close to the surface can be significant.

Here we will show how single terrylene molecules in a p-terphenyl matrix can be evanescently coupled to the guided modes of optical nanofibers. This presents a new platform based on solid state emitters that is used for quantum optics and can be naturally integrated into any optical fiber based quantum network.
