75‐4: Late‐News Paper: Metalens‐Integrated Augmented Reality (AR) Waveguides for Eye‐tracking: A Proof of Concept

We demonstrate a proof‐of‐concept metalens‐integrated AR waveguide for imaging and eye‐tracking. The 4.5 mm metalens is stacked onto a diffractive exit‐pupil‐expander structure to provide aberration‐free imaging. The combined system achieves a 17×16.8‐degree field of view and an 11×9 mm eye box, currently limited by the waveguide's architecture and efficiency.
