    How Four Diffractive Optical Waveguide Pathways Drive Volume Manufacturing

    SRG diffractive optical waveguides use four complementary pathways - nanoimprint, DUV lithography etching, SiC substrates and single-layer full color - to improve mass production, precision, field of view and image quality respectively. The article cites AAC Technologies' single-layer full-color SRG mass production yield of over 80%, a 52-degree FOV for the SiC solution, and the commissioning of Goertek Optics' 12-inch DUV lithography etching production line. Plans for million-unit-level capacity and ramp-up do not mean the industry as a whole has achieved stable million-unit-scale delivery; cost, yield and whole-device integration remain the next hurdles.

    Why we recommend it: Discussing nanoimprint, DUV etching, SiC substrates and single-layer full color separately helps distinguish the constraints on waveguide mass production, precision, field of view and image quality.

    Fanchuangwei High-Transparency Optical AR Lens Project Lands in Taizhou with Total Investment of About RMB 550 Million

    Shanghai Fanchuangwei Technology's high-transparency optical AR glasses lens project has settled in Huangyan, Taizhou, to be carried out in two phases by Fanke Technology (Taizhou), with total investment of about RMB 550 million. Phase one, at about RMB 150 million, plans to complete an innovation center and pilot production line by 2027. Phase two, at about RMB 400 million, targets annual output of 100 tonnes of high-purity silicon carbide optical material by 2028. Aimed at AI glasses and AR terminals, the project covers the full chain from optical materials and etching processes to optical devices.

    Why we recommend it: The source gives the investment figures for both phases, production line timelines and a target of 100 tonnes of silicon carbide optical material per year, useful for gauging the pace of silicon carbide waveguide industrialization.

    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.

    Dinglong Expands into Optical Communications Materials

    Dinglong said at an investor relations event that the explosive growth in AI computing demand is driving optical communications toward higher speeds, placing greater demands on key upstream materials. The company is therefore expanding into high-end core optical communications materials.
