Abstract
We propose a two-colour scheme of atom guide and 1D optical lattice using evanescent light fields of TE00 and TE01 transverse modes in an optical waveguide. The optical waveguide carries red-detuned light and 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.
