CHAIR

Pablo Albella
University of Cantabria
Spain
 
Brief Bio
Pablo Albella holds a prestigious researcher position (RyC), at the University of Cantabria and is invited researcher at Imperial College London. He holds a PhD in Physics since 2009 awarded with the prize of best thesis in physics that year. He was postdoctoral researcher from 2010 to 2013 at the Material Physics Center (UPV/CSIC) in San Sebastian, from 2013 to 2017 senior research associate at Imperial College London, UK and tenure-track researcher at University of Las Palmas de Gran Canaria, Spain. His research interests and activities are mainly devoted to the fields of nanophotonics and materials science. In particular, to the optical modelling and innovation of photonic structures able to enhance the performance of the actual nanodevices that rely on light-matter interaction to boost applications like sensing, spectroscopy, optical nanocircuits, customized metamaterials or energy storage. He aims to, not only the electromagnetic understanding and application of plasmonics, but also to open new fascinating possibilities in the field using novel nanostructures made of alternative materials.

SCOPE

The interaction between light and small clusters of nanoscale metallic and/or dielectric components has been a recent subject of extensive experimental and theoretical research. Knowledge and understanding of the near- and far-field optical responses from individual and coupled nanoparticles have led to an unprecedented development in the fields of molecular optics, optical antenna design, surface enhanced spectroscopies, bio/chemical sensing, light guiding, solar cell system, information storage and other. Research of light-matter interaction at the nanoscale now presents an opportunity to build on the existing work or/and establish novel directions for this area of research.

We invite researchers to contribute with original research ideas that will stimulate the continuing reports to exploit the great potential that light-matter interaction have for real life applications but also to develop this field for future nanophotonic devices.

Numerical Simulation and Optimization of Resonant Nanophotonic Devices

Sven Burger
Zuse Institute Berlin
Germany


Brief Bio
Sven Burger heads the Computational Nano Optics research group at Zuse Institute Berlin, Germany. He is further a member the Mathematics research center MATH+, and of the board of JCMwave, a spin-off company from Zuse Institute Berlin. He received a PhD in physics from the University of Hannover, Germany, and worked as a postdoc at LENS, Florence, Italy. His current research fields are in modelling, simulation and optimization related to applications in optics and photonics.


Abstract
In this lecture, recent numerical methods for the investigation of nanophotonic devices will be reviewed. This includes contour-integration methods for solving eigenvalue problems and for modal expansions of light fields in resonant systems, based on Riesz projections. Adaptive finite-element methods for error-controled simulation of Maxwell's equations will be presented. Also, results on Bayesian optimization methods for parameter reconstruction and for design optimization will be presented. Further, applications to single photon sources and other topical devices will be discussed.

Brief Bio
Costantino De Angelis, born in Padova-Italy, received the Laurea degree (cum laude) in Electronic Engineering and the Ph.D. in Telecommunications from the University of Padova, in 1989 and 1993, respectively.
Since 1998 he is with the University of Brescia, where he is Full Professor of Electromagnetic Fields. In 2010 and 2011 ha has been appointed as Visiting Professor at the Massachusetts Institute of Technology.
He has been former Director of the Department of Information Engineering of the University of Brescia, Coordinator of the research activities of the Department of Information Engineering, Coordinator of the Ph.D. School of Information Engineering, and he is deputy of the Rector for the Ph.D. programme of the University of Brescia.
He is Fellow Member of the Optical Society for significant contributions to the field of discrete and periodic nonlinear photonic structures and to the design of nano-antennas and nonlinear nano-photonic devices. 
His technical interests are mainly in nonlinear optics (soliton propagation, harmonic generation and frequency conversion) and in nanophotonics (optical antennas, metasurfaces, novel photonic devices for image processing and sensing applications, optics of metals, computational electromagnetism). 
His research is devoted to conceiving new devices able to foster light-matter interactions at the nanoscale to facilitate the generation, propagation, manipulation, and detection of light.
He has authored or co-authored more than 400 among papers and conference contributions and he is and has been principal investigator in several European and national funded research project.


Abstract
Optically resonant metasurfaces are an emerging and promising area of nanophotonics. Recently, active tuning of the linear response and nonlinear effects of these components have received an increasing amount of interest. However, so far, these research directions have remained separated with only few sporadic works that study their combination beginning to appear in the literature. The evolution of nonlinear metasurfaces toward reconfigurable and dynamic components could potentially answer the demand of integrated on-chip components that realize essential functionalities such as sum and difference frequency generation, active switching, optical isolation, and optical analog computing. I will present here our recent investigations in this field [1, 2].

Multipole Analysis of Optical Resonances and Quasi-BIC Responses of Dielectric Nanoparticle Structures

Andrey Evlyukhin
Leibniz University Hannover
Germany


Brief Bio
Andrey Evlyukhin is a graduate (with honor) of the Faculty of Physics of Lomonosov Moscow State University, where he was also awarded PhD (1995) and Doctor of Science (habilitation, 2008) degrees. He has the academic title of Associate Professor since 2004. Currently, he works at the Institute of Quantum Optics of the Leibniz University of Hannover, where he is involved in research activity within the Cluster of Excellence PhoenixD in the framework of Germany’s Excellence Strategy. Prof. Evlyukhin is one of the first developers of modern dielectric nanophotonics. He has made landmark original contributions to the study of light scattering by silicon nanoparticles which support the resonant optical responses of magnetic and electrical types. In particular, it has been suggested the idea to shift magnetic dipole resonance in the visible spectral range by using silicon nanoparticles for the realization of corresponding magnetic metamaterials and metasurfaces. The list of his achievements also includes the development of the concept of anapole states in dielectric nanoparticles. The results of his work on the multipole response of dielectric nanoparticles of arbitrary shape have found application in the practical implementation of all-dielectric devices and metasurfaces with different functional properties. Due to his important scientific achievements, Prof. Evlyukhin became one of the internationally renowned scientists in the field of dielectric nanophotonics. Currently, he has a wide international network of his students and followers.


Abstract
A theoretical approach to the multipole analysis of the extinction and scattering spectra of arbitrary shaped particles and the reflection and transmission spectra of metasurfaces composed of them is demonstrated and discussed. The method is applied to high refractive index nanoparticles with isotropic and bianisotropic optical properties supporting optical resonances of both electrical and magnetic types. It is shown how specially configured scattering patterns can be related to the overlap of different multipole modes resonantly excited in nanoparticles and how small shape defects can generate a bianisotropic optical response of single nanoparticles. It is also discussed how it is possible to realize quasi-BICs (quasi-trapped modes) of metasurfaces, consisting of nanoparticles with isotropic and bianisotropic properties, and to provide high-quality optical resonances in the transmission and reflection spectra. A general strategy for the implementation of electric and magnetic quasi-BICs located at the same spectral position is presented.
