Editorial for focus collection on nanophotonics and nano-optics

摘要

The Focus Collection on Nanophotonics and Nano-optics includes original research and review articles on the experimental and technological aspects of light-matter interactions at the nanometer scale. The convergence of photonics and nanotechnology has spawned a rich variety of new materials and applications in plasmonics, photonic crystals and metamaterials. The contributions to this Focus Collection include fundamental material properties such as amorphous hydrogenated silicon carbonitride (Khatami et al), 2D transition metal dichalcogenides (Lepeshov et al), III-V nanowires (Ren et al) and quantum dots (Kuyanov et al); as well as applications in devices including solar cells (Anttu et al) and photodetectors (Kuyanov et al, Ren et al). The potential of anapole states in lasing, sensing, metamaterials and nonlinear optics is reviewed in an article by Yang et al. Hahn et al reveal a resist-on-metal bilayer lift-off technique enabling the fabrication of plasmonic structures on insulating substrates. Several articles describe the potential of nanowires in photonic devices. Nanowires exhibit unique optical resonances that depend on the nanowire diameter, thus enabling either broadband optical absorption for more efficient photovoltaic devices, or narrowband absorption for multispectral photodetectors and cameras. These and other articles of this Focus Collection summarize recent progress in nanophotonics that spans materials, devices and systems.
