Synthetic dimension in photonics

Physics, especially topological physics, depends strongly on the dimensionality of space. There are a number of topological physics effects that are achievable only in high dimensional systems. The concept of synthetic dimensions is developed to explore high dimensional physics in low dimensional physical systems. In this talk, we highlight that photonics provide a powerful platform for implementing synthetic dimension. We discuss our theoretical efforts in constructing a variety of system exhibiting synthetic dimensions, as well as our experimental efforts leading to the demonstration of a quantum Hall ladder for photons. In additional to fundamental physics, we also discuss some of the potentials for the concept of synthetic dimension in optical computing applications.

Shanhui Fan is a Professor of Electrical Engineering, a Professor of Applied Physics (by courtesy), a Senior Fellow of the Precourt Institute for Energy, 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 applications. He has published over 550 refereed journal articles, has given over 350 plenary/keynote/invited talks, and was granted 62 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 W. O. Baker Award for Initiative in Research (2007), the Adolph Lomb Medal from the Optical Society of America (2007), and a Vannevar Bush Faculty Fellowship from the U. S. Department of Defense (2017).  He is a Thomson Reuters Highly Cited Researcher in Physics since 2015,  and a Fellow of the IEEE, the American Physical Society, the Optical Society of America,  and the SPIE.
