报告摘要：

        Nanoscale optics is usually associated with plasmonic structures made of metals such as gold or silver. However, plasmonics suffers from high losses of metals, heating, and incompatibility with CMOS fabrication processes. Recent developments in the nanoscale optical physics has lead to a new branch of nanophotonics aiming at the manipulation of optically-induced Mie resonances in dielectric and semiconductor nanoparticles with high refractive index. Such particles offer unique opportunities for reduced dissipative losses and large resonant enhancement of both electric and magnetic near-fields. Semiconductor nanostructures also offer longer excited-carrier lifetimes and can be electrically doped and gated to realize subwavelength active devices.  These recent developments revolve closely around the nature of the optical resonances of the structures and how they can be manipulated in individual entities as well as complex particle arrangements such as metasurfaces. Resonant high-index dielectric nanostructures form new building blocks to realize unique functionalities and novel photonic devices.

报告人简介：

        Prof Miroshnichenko obtained his PhD in 2003 from the Max-Planck Institute for Physics of Complex Systems in Dresden, Germany. In 2004 he moved to Australia to join the Nonlinear Physics Centre at ANU. During this time he made fundamentally important contributions to the field of photonic crystals and bringing the concept of the Fano resonances to nanophotonics. In 2007 he was awarded by Australian Postdoctoral and in 2011 by Future Fellowships from the Australian Research Council. Recently, he has moved to the University of New South Wales Canberra and got very prestigious Scientia Fellow (effective next year). Currently, he is also Adjunct Professor at Soochow University. The topics of his research are nonlinear nanophotonics, nonlinear optics, resonant interaction of light with nanoclusters, including optical nanoantennas and metamaterials.
