An integrated, ultrafast, optical neuromorphic processor that: Realises an arbitrary Turing machine that can represent any arbitrary defined function of a multidimensional space of coordinates varying with time. It has the same expressive power of state of the art...

Designing light sources with controllable properties at the nanoscale is a main goal in research in photonics. Harnessing disorder opens many opportunities for reducing the footprints of laser devices, enabling physical phenomena and functionalities that are not...

Nanophotonics is a rapidly developing field of research with many suggestions for a design of nanoantennas, sensors and miniature metadevices. Despite many proposals for passive nanophotonic devices, the efficient coupling of light to nanoscale optical structures...

Superradiance—a cooperative phenomenon originally predicted by Dicke in 1954 for two-level atoms—consists of ubiquitous collective dynamics. Such an effect has been observed in a huge number of systems, both quantum and classical. Despite a large body of theoretical...

A spaser is a nanoplasmonic counterpart of a laser, with photons replaced by surface plasmon polaritons and a resonant cavity replaced by a metallic nanostructure supporting localized plasmonic modes. By combining analytical results and first‐principle numerical...

The interaction of light with nanostructured materials provides exciting new opportunities for investigating classical wave analogies of quantum phenomena. A topic of particular interest forms the interplay between wave physics and chaos in systems where a small...

One of the most fascinating possibilities enabled by metamaterials is the strong reduction of the electromagnetic scattering from nanostructures. In dielectric nanoparticles, the formation of a minimal scattering state at specific wavelengths is associated with the...

All-dielectric metamaterials are a promising platform for the development of integrated photonics applications. In this work, we investigate the mutual coupling and interaction of an ensemble of anapole states in silicon nanoparticles. Anapoles are intriguing...

Nonradiating sources of energy have traditionally been studied in quantum mechanics and astrophysics but have received very little attention in the photonics community. This situation has changed recently due to a number of pioneering theoretical studies and...
