In this paper a novel apodization technique using a combination of a phase mask with an amplitude mask of variable mark-space ratio for fabricating sampled Bragg gratings is presented. By this technique it needs only single exposure process instead of double exposure in usual approaches to complete apodization and its compensation in the fabrication. From our numerical simulation and experimental results, it can be seen that this technique is promising in changing reflection spectrum and reducing the ripple of group velocity delay of the sampled fiber Bragg gratings.
