Hangzhou, China – The results of the highly anticipated “2025 Top 10 Socially Influential Optical Events in China (Light10)” selection have been announced. The technological achievement of the “3.8-gram ultralight, mass-producible, rainbow-artifact-free silicon carbide (SiC) AR waveguide,” jointly developed by the team of Professor Min Qiu from the School of Engineering at Westlake University and the teams of Dr. Kaikai Du and Dr. Lu Cai from Moldnano(Hangzhou) Technology Co., Ltd, has been honored with a nomination award in this selection.

The “Top 10 Socially Influential Optical Events in China (Light10)” is an annual public-interest science outreach event co-initiated and organized by the leading journal Light: Science & Applications and Sciencenet.cn under the China Science Daily. Since its inception in 2019, Light10 has successfully held seven sessions, aiming to select and showcase significant optical innovations from China that address global frontiers, national needs, and social welfare, thereby translating “hard tech” into publicly perceivable social value beyond professional barriers. This year's selection attracted over 56,000 participations within just three days, demonstrating its broad impact.

The award-winning SiC AR waveguide technology represents a disruptive breakthrough in the field of augmented reality (AR) displays. This achievement marks the first full-chain, mass-production-ready breakthrough from design and manufacturing to packaging for a single-layer SiC diffractive waveguide. The research team innovatively proposed a “Nanoimprint Lithography lift-off (NIL-to-lift-off)” process, successfully overcoming the precision machining challenges of the hard and brittle SiC material, enabling high-precision, large-scale manufacturing on 4-inch wafers.
