Ultrathin optical fibers (see Fig. 1), with diameters on the order of the propagating light wavelength, have already demonstrated their versatility across a number of different areas, such as sensing, microparticle manipulation, cold atom physics, and as optical couplers.

We present recent work on the integration of ultrathin optical fibers into a cold 87Rb system, for exploring multiphoton processes and the generation of Rydberg atoms near a dielectric surface. Fabrication of structured ultrathin fibers will also be discussed.

We study spontaneous emission from a multilevel atom into the fundamental and higher-order modes of a vacuum-clad ultrathin optical fiber. We examine the dependencies of the rate on the type of modes, the position of the atom, and the fiber radius.
