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 …

The scattering of electromagnetic waves by resonant systems is determined by the excitation
of the quasinormal modes (QNMs), ie the eigenmodes, of the system. This Review …

Acoustic graphene plasmons are highly confined electromagnetic modes carrying large
momentum and low loss in the mid-infrared and terahertz spectra. However, until now they …

The specificity of modal-expansion formalisms is their capabilities to model the physical
properties in the natural resonance-state basis of the system in question, leading to a …

We introduce a second quantization scheme based on quasinormal modes, which are the
dissipative modes of leaky optical cavities and plasmonic resonators with complex …

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

Electromagnetic cavity modes in photonic and plasmonic resonators offer rich and attractive
regimes for tailoring the properties of light–matter interactions, yet there is a disturbing lack …

Control over the optical response of metal nanoparticles and their associated plasmons is
currently enabling many promising applications in areas as diverse as biosensing and …

This review focuses on structural engineering of lasers from the macroscale to the
nanoscale, with an emphasis on plasmon nanolasers. Conventional lasers based on Fabry …

Strong coupling between resonant states is usually achieved by modulating intrinsic
parameters of optical systems, eg, the refractive index of constituent materials or structural …
