This Review focuses on the integration of plasmonic and dielectric metasurfaces with
emissive or stimuli-responsive materials for manipulating light–matter interactions at the …

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 …

Carbon dots (CDs) are a new solution-processable laser material. They offer advantages of
non-toxicity, low cost, and high stability, making them attractive for the sustainable …

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

In recent years, notions drawn from non-Hermitian physics and parity–time (PT) symmetry
have attracted considerable attention. In particular, the realization that the interplay between …

The invention and development of the laser have revolutionized science, technology, and
industry. Metal halide perovskites are an emerging class of semiconductors holding …

In the last two decades, plasmon resonance in gold nanoparticles (Au NPs) has been the
subject of intense research efforts. Plasmon physics is intriguing and its precise modelling …

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 …

Fano resonance is a universal phenomenon observed in many areas where wave
propagation and interference are possible. Fano resonance arises from the interference of …

Here we present a roadmap on Photonic metasurfaces. This document consists of a number
of perspective articles on different applications, challenge areas or technologies underlying …
