Xingjie Ni
Xingjie Ni is a leading figure in nanophotonics, metamaterials and metasurfaces, and optical materials and devices.
Nominators said his transformative research has advanced the understanding and engineering of light-matter interactions at the nanoscale, with national and international impact across sensing, compact imaging systems, communications, quantum technologies and energy-efficient computing. The work has the greatest impact in optical computing for AI (artificial intelligence) efficiency, deployable ultracompact meta-optics and high-density integrated photonics.
Nominators said his devices do not merely improve performance, they shift the design space, enabling unprecedented capabilities that traditional optics and electronics cannot reach in size, speed or power.
“As data growth collides with energy limits, Dr. Ni — building on the work mentioned above — offers a highly innovative path: treating light not only as a signal to be sensed but as a medium that can compute, route and reveal information with minimal power and near-zero latency,” a nominator said. “The cross-industry pain points are clear — AI workloads face power and memory walls; imaging for phones, augmented and virtual reality, drones, and small satellites must shrink without sacrificing fidelity; and networks require denser, more efficient photonics. Ni tackles these bottlenecks by redesigning light-matter interactions at the nanoscale and translating those advances through to manufacturable systems.”
Nominators said Ni’s research addresses challenges that extend far beyond a single field, carrying solutions from fundamental materials and device innovation all the way to scalable, manufacturable technologies. His group uses metasurfaces, ultrathin films patterned at the nanoscale level, to control light with exceptional precision, nominators said. This dramatically shrinks devices such as cameras while also making imaging more informative, reducing AI computing costs by letting light perform part of the computation.
“Ni’s research unites fundamental insight with foundry-ready engineering, translating breakthroughs into scalable, reliable systems,” a nominator said. “The benefits are tangible: lighter cameras with instrument-grade performance, single-shot imagers that capture rich spectral and polarization data, and dramatically lower energy use for AI and optical networks. These advances are already changing how information is sensed, processed, and transmitted, with impact extending from clinics and farms to data centers and mobile devices.”
Nominators said Ni has an excellent record of external funding, student mentoring and professional service. His current research, as principal or co-principal investigator, is supported by more than $11 million provided by the Air Force Office of Scientific Research, NASA, the National Science Foundation, the National Institutes of Health, Raytheon Technologies and Sony Corporation. His former doctoral advisees have advanced to leading industries, national laboratories and universities.
Ni is a fellow of Optica and a member of the American Physical Society, the Materials Research Society, SPIE — the international society for optics and photonics — and the Applied Computational Electromagnetics Society. He serves as an associate editor for Science Advances and the IEEE Journal of Quantum Electronics, and as faculty adviser to the Optica/SPIE Penn State Student Chapter.
“Ni’s visionary research and leadership have profoundly impacted the field of nanophotonics and metamaterials,” a nominator said. “His ability to bridge fundamental science with practical applications sets him apart as a leader in our field. I am confident that his continued contributions will shape the future of science and technology.”
