Abstract
We design and integrate free-form metagratings with irregular nanoscale patterns into diffractive augmented reality (AR) waveguides to achieve simultaneous improvements in eye-glow attenuation and outcoupling efficiency. The freeform metagrating demonstrates over 40% reduction in eye-glow while enhancing outcoupling efficiency by 8% compared to the conventional binary grating.
