Nanofibers as light-matter interfaces for quantum networks — •Dominik Maxein, Baptiste Gouraud, Adrien Nicolas, Elisabeth Giacobino, and Julien Laurat — Laboratoire Kastler Brossel, Université P. et M. Curie, École Normale Supérieure, and CNRS, 4 place Jussieu, 75252 Paris Cedex 05, France

An interesting and emerging system for light-matter interfacing is the optical nanofiber, where light is guided by a “glass wire” with sub-wavelength diameter. The strong evanescent field can yield strong interactions between guided light modes and matter in the surroundings of the nanofiber. To hold an ensemble of atoms in the vicinity of the fiber, two-color optical dipole traps have been recently realized [Vetsch et al., PRL 104, 203603 (2010) and Goban et al., PRL 109, 033603 (2012))].

Our group focuses on the development of quantum memories in cold, neutral atom clouds. We are currently building a work bench for the production of nanofibers using the brushing flame technique, heating a small portion of the fiber and pulling in a well-controlled way. We will present the technological background and characterization for our system and the first obtained tapered fibers. Future applications will be discussed.
