Abstract
A rigorous three-dimensional vector analysis of diffraction by a slanted-fringe anisotropic grating is presented for an arbitrary angle of incidence in three dimensions. The exact formulations of the grating diffraction problem without approximations are presented in terms of characteristic waves and coupled waves. Then, using a series of assumptions, rigorous theory is shown to reduce to various existing approximate theories in the appropriate limits. Planar grating diffraction theory hierarchy is presented. A comparison of diffraction efficiency results from exact rigorous theory and from approximate Kogelnik's theory is made.
