SUMMARY:Chiral Meta-photonics with Bound States in the Continuum
DESCRIPTION:Speaker\nProf. Cheng-Wei QIU\nDepartment of Electrical and Computer Engineering\,\nNational University of Singapore \nAbstract\nIn this talk\, the recent progress on how chirality could transcend designs of advanced metasurfaces\, sensing\, BIC photonics and optical micromanipulations will be presented. In particular\, recent results will be reported on the realization of intrinsic chiral metasurfaces where the engineered slant geometry breaks both in-plane and out-of-plane symmetries. The achieved results include intrinsic chiral bound states in the continuum with near-unity CD of 0.93 and quality factor exceeding 2300 for visible frequencies. Finally\, new perspectives on using photonic orbit angular momentum to effectively discriminate single-size and multi-scale chiral nanostructures will be discussed. \nBiography of the Speaker \nProf. Cheng-Wei QIU is appointed IEEE Photonics Society Distinguished Lecturer 2024. He is Fellow of APS\, Optica\, SPIE and The Electromagnetics Academy\, US. He was the recipient of President’s Science Award 2023\, the highest science accolade in Singapore. He was elected Fellow of ASEAN Academy of Engineering and Technology. He is well known for his research in structured light and interfaces. He has published over 480 peer-reviewed journal papers. He was the recipient of URSI Young Scientist Award in 2008\, NUS Young Investigator Award in 2011\, MIT TR35@Singapore Award in 2012\, Young Scientist Award by Singapore National Academy of Science in 2013\, Faculty Young Research Award in NUS 2013\, SPIE Rising Researcher Award 2018\, and Engineering Researcher Award 2021 in NUS\, and World Scientific Medal 2021 by Institute of Physics\, Singapore\, Achievement in Asia Award (Robert T. Poe Prize) by International Organization of Chinese Physicists and Astronomers in 2022. He was Highly Cited Researchers in 2019\, 2020\, 2021\, 2022\, 2023 by Web of Science. He has been serving in Associate Editor for various journals such as JOSA B\, PhotoniX\, Photonics Research\, and Editor-in-Chief for eLight. He also serves in Editorial Advisory Board for Laser and Photonics Review\, Advanced Optical Materials\, and ACS Photonics. \nOrganizer: Prof. Kevin TSIA \nAll are welcome! We look forward to seeing you!
