“…Surface plasmon polariton spasers have been demonstrated in 1D and 2D configurations [61], [82], [239], [311]. Such hybrid nanolasers have attracted significant attention because they combine the benefits of small mode volumes of plasmon modes and strong gain parameter in highindex semiconductors [343]. For example, in [61] a 1D plasmonic laser consisting of a CdS semiconductor nanowire (NW) on top of an Ag substrate has been realized, Fig.…”

Recent progress in nanofabrication has led to tremendous technological developments in nanophotonics, which rely on the interaction of light with nanostructured matter. Nanophotonics has experienced a large surge of interest in recent years, from basic research to applied technology.The increased importance of extremely low-energy data processing at ultra-fast speeds has been encouraging the use of light for signal transport and processing. Energy demands and interaction time scales become smaller with the physical size of the nanostructures, hence nanophotonics opens the opportunity of integrating a large number of devices that can generate, control, modulate, sense and process light signals at ultrafast speeds and below femtojoule/bit energy levels.However, losses and diffraction pose fundamental challenges to the fundamental ability of nanophotonic structures to confine light efficiently in smaller and smaller volumes. In this framework, active nanophotonics, which combines the latest advances in nanotechnology with gain materials, has become in recent years a vital area of optics research, both from the physics, material science, and engineering standpoint. In this paper, we review recent efforts in enabling active nanodevices for lasing and optical sources, loss compensation, and to realize new optical functionalities, like -symmetry, exceptional points and nontrivial lasing based on suitably engineered distributions of gain and loss in nanostructures.

“…The optimizations of our proposed scheme consist of two parts: (i) the nanoring structure, and (ii) the outcoupling efficiency aer the introduction of a butt-joint outcoupling waveguide, but with more emphasis on the latter. The former is briey mentioned for the sake of completeness, since extensive optimization on the nano-ring laser has been published before, 16 and the results are adapted into our model here. We utilize the design with two cavity resonance cycles, m ¼ 2, in our simulation, since the case with m ¼ 1 has already been presented in ref.…”
