The Semiconductor Division of Hon Hai Research Institute (HHRI) , a subsidiary of Hon Hai Technology Group, the world's largest technology manufacturing platform service company, has once again broken through technological boundaries, successfully developing the world's first monolithically integrated metasurface-photonic crystal surface-emitting laser (meta -PCSEL) technology for depth sensing systems, significantly advancing the application of spatial computing.

This technological breakthrough was achieved by Director Guo Haozhong of the Semiconductor Division of Hon Hai Research Institute and Chair Professor at National Yang-Ming National Chiao Tung University, in collaboration with Group Leader Hong Yuheng, Researcher Xu Yezheng, and Researcher Miao Wenqian of the Semiconductor Division, and a research team led by Assistant Professor Huang Yaowei of National Yang-Ming National Chiao Tung University. The related paper, " Monolithically Integrated Metasurface on a PCSEL for Depth Perception ," has been published in the leading global journal Nano Letters * and was selected as the journal's cover story for the July 2025 issue.

Compared to traditional dot projectors, this chip-scale projection technology boasts an ultra-small footprint of 0.025 mm³ , making it the world's smallest projector. Compared to dot projectors used in commercial mobile phones, its volume is approximately 2,450 times smaller, while power consumption is reduced by 28.7% . This single-chip integration technology enables significant system miniaturization and overall power savings, opening up new possibilities for spatial computing in mobile devices, wearables, and augmented reality (AR) applications.

Single-chip integration technology significantly reduces system complexity and energy consumption, providing more competitive solutions for industrial applications. This technological breakthrough not only demonstrates Foxconn's leading position in nano-optics and semiconductor technology, but also lays the foundation for future applications of spatial computing. Looking ahead, this technology will accelerate the popularization of AR , VR , and smart wearable devices.
