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 …

Frequency conversion processes, such as second-and third-harmonic generation, are
commonly realized in nonlinear optics, offering opportunities for applications in photonics …

Sharp electromagnetic resonances play an essential role in physics in general and optics in
particular. The last decades have witnessed the successful developments of high-quality (Q) …

Recent progress in nanoscale optical physics is associated with the development of a new

The scattering of electromagnetic waves lies at the heart of most experimental techniques
over nearly the entire electromagnetic spectrum, ranging from radio waves to optics and x …

Interference of electromagnetic modes supported by subwavelength photonic structures is
one of the key concepts that underpins the nanoscale control of light in metaoptics. It drives …

Optical bound states in the continuum (BICs) underpin the existence of strongly localized
waves embedded into the radiation spectrum. Here we bring the concept of BICs to the field …

The toroidal dipole is a localized electromagnetic excitation independent from the familiar
magnetic and electric dipoles. It corresponds to currents flowing along minor loops of a …

We present strong enhancement of third harmonic generation in an amorphous silicon
metasurface consisting of elliptical nano resonators. We show that this enhancement …
