Abstract: Augmented Reality (AR) is emerging as the next-generation computing platform after mobile computing; however,its core optical display systems still grapple with significant challenges in the field of view(FOV),full-color reproduction,and lightweight design.This paper presents an optical metasurfacebased AR waveguide technology that precisely manipulates light fields using subwavelength structures, aimed at systematically addressing the inherent limitations of conventional difractive waveguide solutions. The paper first analyzes the current technological landscape and commercialization progress within the AR market, identifying existing constraints,and delves into the metasurface waveguides’ core physical principles and design methodologies.To facilitate industrialization,this paper introduces an integrated metasurface waveguide design and manufacturing platform. The crucial role of high-directionality light sources in the evolution of AR displays is also highlighted.Research results indicate that metasurface waveguides can efectively overcome the performance limitations of traditional diffractive waveguides, demonstrating immense potential in expanding FOV,achieving high-fidelity full-color displays,and significantly reducing device weight.This offers a highly eficient and integrated innovative solution for next-generation AR display systems. Finall,the paper explores the profound strategic implications of this technological pathway for the future spatial computing industry,foreseing its foundational role in the widespread adoption and diverse applications of AR devices.
