Most 3D augmented reality, near-eye displays suffer from a low field of view. Leaky-mode lithium niobate devices are often used to steer, multiplex, or otherwise control the path of light in a system. Such devices are ideal candidates for creating such displays, and, in this paper, we demonstrate a path to increasing their view angle to 180° by curving the substrate, which will steer the output light toward the user’s eye. We also model the tradeoff between field of view, allowable interaction length, and draw distance for these curved leaky-mode devices.
