About

Yu Han Chen is a pioneering researcher in the field of nanophotonics and metasurface optics, whose work has significantly advanced the development of ultra-compact optical systems. Chen's research focuses on the design and fabrication of metalenses — flat optical elements engineered at the nanoscale to manipulate light with extraordinary precision. Their most celebrated contribution, the 2019 paper "Achromatic metalens array for full-colour light-field imaging," has garnered an impressive 664 citations, underscoring its transformative impact on the field. This landmark work addressed one of the most persistent challenges in flat optics: chromatic aberration. By engineering a metalens array capable of focusing multiple wavelengths simultaneously without color distortion, Chen demonstrated a viable pathway toward high-performance, miniaturized imaging systems that could revolutionize everything from smartphone cameras to medical endoscopes. The achievement bridged fundamental nanophotonic science with practical imaging applications, inspiring numerous subsequent studies in computational imaging and next-generation optical devices. Chen's contributions represent a compelling fusion of materials science, photonics, and optical engineering, establishing them as a notable voice in the rapidly evolving landscape of flat optics research.
