A model for slanted volume holographic grating based on the rigorous coupled-wave analysis (RCWA) is proposed and analyzed. In this model an oblique coordinate system related to the grating fringes simplifies the mathematical analysis. And the S-matrix algorithm gives the RCWA results. Based on the vector theory, the RCWA can present more details of the diffraction process. Compared with the traditional approximate theory, the RCWA for volume grating can analyze the angular selectivity and the diffraction efficiency more accurately and flexibly. Through the simulation results, the Fresnel diffraction on the interface can be analyzed. The effect of the grating fringe error the grating is also provided. The effect of the grating thickness, an important grating parameter, has been described particularly.
