Abstract
Future technologies underpinning high-performance optical communications, ultrafast computations, and compact biosensing will rely on densely packed reconfigurable optical circuitry based on nanophotonics. For many years, plasmonics was considered as the only available platform for subwavelength optics and nanophotonics, but the recently emerged field of Mie resonant metaphotonics (or Mie-tronics) provides practical alternatives for nanoscale optics by employing resonances in high-index dielectric nanoparticles and metasurfaces. In this talk I aim to introduce this recently emerged new field and discuss the physics of dielectric Mie-resonant metamaterials for efficient spatial and temporal control of light by employing multipolar resonances and bound states in the continuum to achieve high values of the Q factor, with applications of these concepts to nonlinear photonics, nanolasers, and sensing.
Biography of Prof. Yuri Kivshar
Prof. Yuri Kivshar received PhD degree in ۱۹۸۴ in Kharkov (Ukraine). From ۱۹۸۹ to ۱۹۹۳ he worked at several research centers in USA and Europe, and in ۱۹۹۳ he moved to Australia where he established Nonlinear Physics Center at the Australian National University. His research interests include nonlinear physics, metamaterials, and nanophotonics. He is Fellow of the Australian Academy of Science, OSA, APS, SPIE, and IOP. He received many awards including Lyle Medal (Australia), Lebedev Medal (Russia), The State Prize in Science and Technology (Ukraine), Harrie Massey Medal (UK), Humboldt Research Award (Germany), SPIE Mozi Award, and more recently ۲۰۲۲ Max Born Award (Optica).
