In this Review, the theory and applications of optical micro‐and nano‐resonators are
presented from the underlying concept of their natural resonances, the so‐called quasi …

We present a biorthogonal approach for modeling the response of localized electromagnetic
resonators using quasinormal modes, which represent the natural, dissipative eigenmodes …

Optical resonators are widely used in modern photonics. Their spectral response and
temporal dynamics are fundamentally driven by their natural resonances, the so-called …

Quantum mechanical interactions between electromagnetic radiation and matter underlie a
broad spectrum of optical phenomena. Strong light-matter interactions result in the well …

Fano resonances in hybridized systems formed from the interaction of bright modes only are
reported. Despite precedent works, we demonstrate theoretically and experimentally that …

Quantum plasmonics is an exciting subbranch of nanoplasmonics where the laws of
quantum theory are used to describe light-matter interactions on the nanoscale. Plasmonic …

Scattering of waves involves different phenomena, but the most common one is the
interference. It has different manifestations, including constructive interference …

Plasmonic modes with long radiative lifetimes combine strong nanoscale light confinement
with a narrow spectral line width carrying the signature of Fano resonances, making them …

Since its discovery, the asymmetric Fano resonance has been a characteristic feature of
interacting quantum systems. The shape of this resonance is distinctively different from that …

We show in detail how a derivation of Fano theory can serve as a new paradigm to study,
understand, and control the interaction of nano-objects with light. Examples include a …
