报告摘要：Surface plasmon polaritons, often shortened to surface plasmons (SPs), represent hybrid excitations involving free electron oscillations in metals and electromagnetic fields in dielectrics that propagate along and strongly bound to metal-dielectric interfaces. These surface electromagnetic waves enable deeply subwavelength confinement of guided modes along with strong enhancement of optical fields, two major features of SP modes that have been and continue being advantageously exploited in plasmon-empowered nanophotonics. In this talk, special attention is given to the progress in ultra-compact photonic circuitry, including modulators and detectors, and plasmonic metasurfaces dynamically controlling propagation of light. Special emphasis is given to the metasurface-enabled generation of single-photon circularly and linearly polarized vortex beams.
报告人简介:
Sergey I Bozhevolnyi is a Professor and Head of Centre for Nano Optics at the University of Southern Denmark (SDU) and a Chair of Technical Science at Danish Institute of Advanced Study. He initiated experimental research in near-field optics at the Institute of Physics, Aalborg University (Denmark) in 1991, where he has been Professor in 2003-2009 before moving to SDU. During 2001–2004, he was also the Chief Technical Officer (CTO) of Micro-Managed Photons A/S set up to commercialize plasmonic waveguide components. His current research interests include linear and nonlinear nano-optics and plasmonics, including plasmonic interconnects, quantum plasmonics and metasurfaces. Prof. Bozhevolnyi is a Fellow of Optical Society of America (2007), elected member of Danish Academy of Natural Sciences (2010) and Danish Academy of Technical Sciences (2019). He has been on the list of Highly Cited Researchers (top 1%) by the Institute of Scientific Information every year since 2017. In 2020, he was awarded the European Physical Society – Quantum Electronics and Optics Division (EPS-QEOD) Prize for Research in Laser Science and Applications for his research in plasmonics and metasurfaces.
