Abstract: Electromagnetic waves, or light, represent a fundamental aspect of nature. New capabilities to control light therefore can have important implications for a wide range of applications including information and energy technologies. In this talk, we will discuss our recent works in seeking to develop a gauge field for photons that breaks time-reversal symmetry of light, which is important for creating non-magnetic one-way non-reciprocal devices on chip that is topologically robust. We will also present recent results in seeking to control thermal radiation with photonic structures, which has led to the experimental demonstration of daytime radiative cooling.
Bio: Shanhui Fan is a Professor of Electrical Engineering, and the Director of the Edward L. Ginzton Laboratory, at the Stanford University. He received his Ph. D in 1997 in theoretical condensed matter physics from the Massachusetts Institute of Technology (MIT). His research interests are in fundamental studies of solid state and photonic structures and devices, especially photonic crystals, plasmonics, and meta-materials, and applications of these structures in energy and information technology. He has published over 330 refereed journal articles, has given over 250 invited talks, and was granted 48 US patents. Prof. Fan received a National Science Foundation Career Award (2002), a David and Lucile Packard Fellowship in Science and Engineering (2003), the National Academy of Sciences Award for Initiative in Research (2007), and the Adolph Lomb Medal from the Optical Society of America (2007). He is a Fellow of the IEEE, the American Physical Society, the Optical Society of America, and the SPIE.
