    Leqi second-generation AI glasses outlook: four optical challenges for diffractive waveguides

    The article argues that AI capabilities can be upgraded over the air, but the optical experience of a diffractive waveguide is hard to fix once finalized. The development of Leqi's second-generation AI glasses focuses on four engineering challenges: hiding the grating, suppressing rainbow artifacts, thinning the lens, and reducing reflections while preserving brightness. These are also the issues consumer AI glasses must solve to look like ordinary eyewear.

    Are DOE and Metasurfaces the Same Thing?

    Citing Yole's 2025 diffractive optics report, the article notes that metasurfaces are a nanoscale subclass of DOE diffractive optical elements, not a replacement. The two have diverged in physical mechanisms, manufacturing routes and industrialization stages: traditional DOEs support today's volume production of AR optical waveguides, while metasurfaces carry future upgrades.

    The Other Side of the First Year of Waveguide Mass Production: Capacity Is in Place, but Is Yield Keeping Up?

    The article argues that 2026 is the first year of optical waveguide mass production, with multiple production capacities of one million units coming online, but capacity expansion does not equal stable mass production. The core barrier has shifted from whether it can be done to whether it can be done consistently at high yield. The three major bottlenecks in materials, processes and inspection are interlinked, requiring end-to-end system capabilities.

    Industry Analysis: Silicon Carbide Waveguides Shift from Performance Option to Mass Production Essential

    An OFweek article analyzes how silicon carbide optical waveguides are moving from an alternative AR performance material to a core element of mass production, with materials, chips and modules all scaling up simultaneously. It cites actions including Aifalong's oversubscribed Series B round of more than 100 million yuan to build an 8-inch silicon carbide metasurface optical waveguide chip production line, Guangna Siwei's financing of nearly 200 million yuan, and Goertek Optics' F50Se module achieving a 50-degree field of view. The author believes cost, processing yield and supply chain maturity remain the three hurdles before large-scale deployment, with the current average price of a SiC waveguide chip at 250-350 US dollars.

    CIOE 2026 AR Optics Review: Mass Production, Thin-and-Light Design and Color Emerge as Keywords

    At the 27th CIOE and SIVA 2026, the keywords for VR/AR optics centered on mass production, thin-and-light design, and color displays for AR glasses. The article summarizes show trends, noting that 4-inch, 6-inch and other semiconductor wafers were everywhere, serving as a way to demonstrate mass-production capability.

    Why we recommend it: The original article summarizes the directions of multiple AR optics makers at the show, making it easy to compare the current state of the AR optics supply chain

    Optical Waveguide Technologies Classified: Five Routes and Five Physical Logics

    The article groups AR optical waveguides into three major categories and five technology routes: geometric, diffractive (including SRG, VHG and PVG) and metasurface. Each relies on different optical principles, performance limits and industrialization timelines, and the article argues that no single solution fits all applications.
