Abstract

Over the past decade, dielectric nanophotonics has emerged as a cornerstone of nano-optics. High index dielectric nanoparticles avoid the large ohmic losses of plasmonic ones, while supporting strong electric and magnetic Mie resonances that enable unprecedented control of light at the nanoscale. The drive of the field stemmed from the realization of optical metasurfaces, which are two dimensional arrays that can control the phase, amplitude and polarization of light with subwavelength resolution. However, the field has rapidly diversified: metasurfaces and metamaterials built from complex dielectric building blocks produce collective resonances that provide unprecedented spatial and temporal confinement of light, boosting light-matter interactions. In parallel, active dielectric platforms are enabling ultrafast tunability of optical functionalities. The interplay of nonlinear and chiral light–matter interactions is opening routes towards compact devices for frequency conversion and spin-selective responses, while concepts rooted in non-Hermitian physics are revealing new paradigms for loss, gain, and exceptional-point engineering. Novel platforms such as “Mie voids” and excitonic materials are broadening even further the design space, promising new exciting applications. In this context, the mini-colloquium will bring together experimentalists and theorists to map the current landscape, identify challenges and strengthen our ongoing European and international collaborations to explore next-generation dielectric nanophotonic devices.
