  Optical dipole traps and fractional Talbot optical lattices based on the
interference between multiple co-propagating laser beams are proposed. The
variation of relative amplitudes and phases of the interfering light beams of
these traps makes it possible to manipulate the spatial position of trapped
atoms. Examples of spatial translation and splitting of atoms between a set of
the interference traps are considered. The prospect of constructing all-light
atom chips based on the proposed technique is presented.
