P‐227: Late‐News Poster: Design Freeform Metagratings for Eye‐glow Attenuation in Diffractive AR Waveguides

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 enha...

Zusammenfassung: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.
