Abstract Random Lasers (RLs) and Random Fiber Lasers (RFLs) have been the subject of
intense research since their first experimental demonstration in 1994 and 2007, respectively …

Structured light is derived from the ability to tailor light, usually referring to the spatial control
of its amplitude, phase, and polarization. Although a venerable topic that dates back to the …

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 provide a self-consistent electromagnetic theory of the coupling between dipole emitters
and dissipative nanoresonators. The theory that relies on the concept of quasinormal modes …

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

The concept of random lasers exploiting multiple scattering of photons in an amplifying
disordered medium in order to generate coherent light without a traditional laser resonator …

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 …

We report an alternative random laser (RL) architecture based on a flexible and ZnO-
enriched cellulose acetate (CA) fiber matrix prepared by electrospinning. The electrospun …

An unusual spectrally reproducible near‐IR random lasing (RL) with no fluctuation of lasing
peak wavelength is disclosed in polycrystalline films of formamidinium tin triiodide …

Random lasing—for which disorder is exploited to enhance stimulated emission—has
emerged as a paradigmatic phenomenon of complex lasers. Random lasers feature unique …
