Using Optical Nanofibers for Quantum Optics — •Sarah M. Skoff, Hardy Schauffert, Johanna Hütner, and Arno Rauschenbeutel — Institute of Atomic and Subatomic Physics, Vienna University of Technology, Stadionallee 2, 1020 Vienna, Austria

Optical nanofibers are a versatile tool for interfacing different quantum emitters with a light field. They are the tapered part of a commercial optical fiber that has a subwavelength diameter waist and therefore allows a significant amount of light to be guided outside the fiber in the form of an evanescent wave. We use such optical nanofibers to optically address individual molecules in solids and we will present this fully fiber-integrated system in more detail.

Due to the transverse confinement of the light field provided by the optical nanofiber, the interaction with quantum emitters is already significant. However this nanofiber-based approach can be combined with a fiber-based cavity to enhance the light-matter interaction even further and we will show the implementation of such a resonator.
