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: Laser ranging with dual-comb nonlinear asynchronous optical sampling and SNSPD

    Our group collaborated with Professor Youjian Song to combine SNSPD with dual-comb ranging, and used the nonlinear asynchronous optical sampling method to measure the distance of an outdoor cooperative target. For a target 298 m away, with an acquisition time of 1 s, the ranging precision is 0.9 micrometers.Relevant research paper was published in Optics Express.URL: https://doi.org/10.1364/OE....
