In the common effort to make quantum signal transmission reliable over arbitrary long distances via quantum repeaters [1], the ability to store and retrieve - or slow down - photons proves necessary. Combining one of the optical mechanisms able to produce slow light, Electromagnetically Induced Transparency (EIT) [2], with a newly developed shell-free hollow-core waveguide allows for the study of enhanced light-matter interaction due to a small mode-volume.
Here, we will focus on the experimental realization of an EIT experiment utilizing this structure. Single mode waveguiding at around the Cs D1 line (894 nm) is demonstrated and protection of the structure against degradation in Cs cell is discussed. First results on Cs spectroscopy supported by the waveguide structure are reported.
