About

Din Ping Tsai is a pioneering researcher in nanophotonics and metasurface optics, whose work has fundamentally advanced the design and application of flat optical devices. Best known for his groundbreaking contributions to metalens technology, Tsai has helped transform how scientists approach miniaturized, high-performance optical systems. His 2019 paper on achromatic metalens arrays for full-colour light-field imaging has garnered over 660 citations, establishing a landmark in overcoming chromatic aberration — one of the central challenges in flat optics — and enabling compact, broadband imaging solutions. Tsai's research extends into optical manipulation, where his work on metamaterial-based optical tweezers offers elegant alternatives to conventional refractive systems, streamlining the tools used across applied and biological physics. His team has also pioneered meta-lens-based edge detection systems capable of operating across one to three dimensions, opening new frontiers in computational imaging. More recently, his "Meta-Lens in the Sky" project demonstrated the real-world viability of GaN-based meta-lens cameras in demanding environments, underscoring the technology's practical potential. Together, these contributions position Tsai as a defining voice in the transition from traditional bulky optics to the next generation of ultra-thin, integrable photonic devices.
