The dual-writing process of holographic technique was applied to fabricate the two-dimensional surface relief gratings on azo-dye doped polymer film in this study. The structure of two-dimensional grooves was investigated under the various polarization state of writing beam, the various angle between two stages of writing, and the adoption of nematic liquid crystals as the interface. The results revealed that the depth of two-dimensional surface relief gratings produced by the writing beams with P-polarization and the interface of nematic liquid crystals in contact with azo-dye polymer film was about 2~3 times of that without nematic liquid crystals as the interface. As the angle between two stages of writing increases, the first order diffraction efficiency and the depth of surface relief structure in the second writing becomes smaller for the writing beam with S polarization; while the first order diffraction efficiency and the depth of surface relief structure becomes larger for the writing beam with P polarization.
