In conjunction with the 11th International Conference on Photonics, Optics and Laser Technology - PHOTOPTICS 2023
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.

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.

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].

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.
