The colloquium is on &#x27;Optical metasurfaces and unusual ultrathin optical devices&#x27;.Driven by miniaturization and integration, there is huge interest in developing ultrathin optical devices with unusual functionalities. Optical metasurfaces can manipulate light propagation in a desirable manner, providing a compact platform to develop ultrathin optical devices that are very difficult or impossible to realize with conventional optics. In this talk, Dr Chen is going to review the recent progress in optical metasurfaces and their applications in ultrathin metasurface devices for imaging, metrology, and information processing. He will mainly focus on our recent work, including metalenses, metaholograms, multifunctional devices, multichannel devices, and metadevices for vortex beam superposition and 3D polarization manipulation.Xianzhong Chen (Sam) is leading the <a href="https://nanophotonicshwu.wixsite.com/xchen" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">Experimental Nanophotonics Group</a> at HWU, which is dedicated to the fundamental physics of metasurface and its application in ultrathin optical devices for imaging, display and information processing. His current main research interests include metalenses, holograms, optical vortex beams and polarization detection. The ultrathin nature and unusual functionalities have enabled the discovery of new phenomena and the development of novel prototype devices for future technologies. To explore the commercial applications of novel nanodevices and integrated optical systems, he has built connections with industry, including STMicroelectronics, Renishaw and Holoxica. He has published over 80 papers, including Nature Communications, Nano Letters, Advanced Materials, and Light: Science &amp; Applications. His previous work on macroscopic invisibility cloaking of visible light was selected as one of the &quot;Top 10 Breakthroughs &quot; by Physics World and “Top 100 Stories &quot; by Discover Magazine. He is one of the Associate Editors of <a href="https://www.frontiersin.org/journals/nanotechnology" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">Frontiers in Nanotechnology</a>.
