We explore light-matter interactions at nanoscale. In particular, we study the phenomena and principles regarding how light/photons interact with dielectric materials, semiconductors, metals, and superconductors that are designed and made into nanostructures by cutting-edge nanofabrication technologies. We furthermore develop novel optoelectronic devices for information processing, storage, and delivery that directly enable applications in sensing, computation, microscopy, communication, and health care. Our research combines electrical engineering, optical engineering, information science, material sciences, and physics, and helps push forward the frontiers of photonics and optoelectronics.

New publication: Enhancement of silicon sub-bandgap photodetection by helium-ion implantation
In collaboration with researchers from the University of Science and Technology of China, Huazhong University of Science and Technology, and Zhejiang University-UIUC Institute, our group used a helium-ion microscope to implant helium ions into silicon with appropriate doses to improve the performance of photodetectors based on sub-bandgap optical absorption effects.
