Abstract
Augmented reality (AR) displays are gaining attention as next‐ generation intelligent display technologies. To further address the demand for a wide field of view (FOV) in AR displays, gradient period polarization volume holographic gratings (PVGs) are proposed as coupling devices for diffractive waveguides. Here, a novel modeling method for gradient period PVGs are proposed by incorporating grating stacking and scattering analysis utilizing rigorous coupled‐wave analysis (RCWA) theory. The diffraction efficiency and polarization response were extensively explored using this simulation model.
