Abstract
We report on the experimental realization of a Bragg reflector for guided matter waves. A Bose-Einstein condensate with controlled velocity distribution impinges onto an attractive optical lattice of finite length and directly probes its band structure. We study the dynamics of the scattering by this potential and compare the results with simple one-dimensional models. We emphasize the importance of taking into account the gaussian envelope of the optical lattice which gives rise to Bragg cavity effects. Our results are a further step towards integrated atom optics setups for quasi-cw matter waves.
