Abstract
A new geometry of optical lattice is proposed, namely a lattice made of a 1D stack of ring traps. It is obtained though the interference pattern of two counterpropagating beams: one of the beam is a standard gaussian beam, while the other one is a hollow beam obtained through a setup with two conical lenses. The resulting lattice is shown to have a high filling rate and a good confinement, so that it could be loaded directly from a MOT with applications in the domain of quantum computing, or with a Bose-Einstein condensate, which would have in this case a 1D ring geometry.
