| Two-color atom guide and 1D optical lattice using evanescent fields of high-order transverse modes (2007) | |||||||||
Abstract | |||||||||
| We propose a two-color scheme of atom guide and 1D optical lattice using evanescent light fields of different transverse modes. The optical waveguide carries a red-detuned light and a blue-detuned light, with both modes far from resonance. The atom guide and 1D optical lattice potentials can be transformed to each other by using a Mach-Zehnder interferometer to accurately control mode transformation. This might provide a new approach to realize flexible transition between the guiding and trapping states of atoms.. Comment: 18 pages, 12 figures, 1 table | |||||||||
