Metamaterials are rationally designed composites aiming at effective material parameters
that go beyond those of the ingredient materials. For example, negative metamaterial …

Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic
nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of …

A bound state in the continuum (BIC) is a nonradiating state of light embedded in the
continuum of propagating modes providing drastic enhancement of the electromagnetic field …

Molecular plasmonics, the area which deals with the interactions between surface plasmons
and molecules, has received enormous interest in fundamental research and found …

Despite the extraordinary degree of interest in optical metamaterials in recent years, the
hoped-for devices and applications have, in large part, yet to emerge. It is becoming clear …

Control of light transmission and reflection through nanostructured materials has led to
demonstration of metamaterial absorbers that have augmented the performance of energy …

Nanolasers generate coherent light at the nanoscale. In the past decade, they have attracted
intense interest, because they are more compact, faster and more power-efficient than …

Light scattering by small particles has a long and interesting history in physics. Nonetheless,
it continues to surprise with new insights and applications. This includes new discoveries …

Plasmon lasers can support ultrasmall mode confinement and ultrafast dynamics with device
feature sizes below the diffraction limit. However, most plasmon-based nanolasers rely on …

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 …
