Owing to exotic optical responses, metallic nanoparticles and nanostructures are finding broad applications in laser science, leading to numerous design variations of plasmonic nanolasers. Nowadays, two of the most intriguing plasmonic nanolasing devices are spasers and random lasers. While a spaser is based on a single metallic nanoparticle resonator with the optical feedback provided by the localized surface plasmon resonance, the operation of a random laser relies on multiple light scattering within randomly distributed metallic nanoparticles. In this paper, an up-to-date review on the applications of metallic nanoparticles in spasers and random lasers is provided. Principles of a random spaser, a device combining the features of a spaser and a random laser, are briefly discussed as well. The paper is focused on major theoretical and experimental approaches to control the core metrics of lasing performance, including threshold, resonant wavelength, and emission directionality. The applications of spasers and random lasers in the fields of sensing and imaging are also mentioned. Finally, the challenges and future perspectives in this area of research are discussed.

“…Finally, binary or ternary blends of conjugated polymers and dyes, or mixtures of these organic compounds with nanoparticles, might lead to outstanding performance through enhanced lasing efficiency, lowered threshold, and reduced photobleaching. Host–guest donor–acceptor systems, consisting of polymer/dye blends or of different conjugated polymers, might exploit nonradiative energy transfer processes to reduce self‐absorption and other sources of optical losses.…”

The potentialities of miniaturized laser sources are still far from being fully developed. Unprecedented opportunities are generated in this field by organic nanowires and nanofibers, which can be used as building blocks of micro‐ and nanolasers in which they combine optical gain, waveguiding, and very high versatility to create nanophotonic networks. The progress in laser devices and network architectures based on optically pumped organic light‐emitting nanowires and nanofibers is here presented, with emphasis on developed active materials, fabrication technologies, lasing mechanisms, and cavity geometries, and on achieved device performance in terms of spectral tunability, excitation threshold, and resonator quality factors. Recent examples of optical coupling of different miniaturized lasers, of their application in optical sensing, and of network lasers are presented. Future directions for research are also outlined, which include the exploration of new classes of active organic or hybrid materials within nanowires, the more in‐depth characterization of the fundamental properties of these lasers, and the use of topologically defined organic nanophotonics in network science, computing, and diagnostics.

Soft‐matter microlasers are an interesting part of soft‐matter photonics, which are based on liquids, liquid crystals, polymers, biological materials, and fabricated mainly by solution‐processing approaches. Soft‐matter microlasers comprehend a multitude of attractive features, including low‐cost, mechanical flexibility, wide range wavelength tunability and, in some cases, biocompatibility, and biodegradability. As such, they are recognized as versatile candidates for efficient light sources with enhanced performances and applications as ultrasensitive physical, chemical, and biological sensors. Here, the recent developments of soft‐matter microlasers are reviewed in time and the prospect in this field is provided. First, the characteristics of the representative soft‐matter microlasers are discussed with focus on their laser structures, lasing mechanisms, fabrication approaches, and gain material origins, followed by an introduction about the current cutting‐edge soft‐technologies that are applied in soft‐matter microlasers. Afterward, their potential applications as wavelength tunable sources, sensors, and displays are highlighted. Finally, the work is summarized and the prospect of soft‐matter microlasers for expanding this emerging research field is presented.
