dc.description.abstractThe main objectives of this thesis were to create and investigate properties and applications of all-optical atomic guides, which are potential building blocks for atom optics experiments. Specifically, we investigated experimentally and theoretically the evolution of the transverse and longitudinal atomic distributions in blue-detuned Bessel tunnels. These tunnels provide confining potentials that are comparable to or higher than the average kinetic energy of cold hundreds of microKelvin) ensembles. The new work highlighted in this thesis include investigations of the following: 1) the generation of Bessel beams using a 2D spatial light modulator (SLM) (both experimental measurement and numerical simulations were performed), 2) the efficiency of the SLM for converting light from a Gaussian beam to a Bessel beam, 3) the behavior of several propagating structures that might be useful for guiding atoms, 4) the atom-tunnel dynamics, 5) an atom switch and delay line (along with measurements of the switch efficiency), and 6) the single-mode propagation in an idealized tunnel. To the best of our knowledge, the work in this thesis constitutes the first time that (1) an atom switch and a delay line have been demonstrated using blue detuned unnels and (2) the atom-tunnel dynamics and thephase-space distribution of a non-interacting dilute gas in a non-equilibrium state has been tracked experimentally.en_US
