Special topic “Dielectric Nanoresonators and Metamaterials” of the Journal of Applied Physics open for submission until Dec. 31st
High-refractive-index (HRI) dielectric nanostructures, and in particular semiconductors, are attracting great attention in Optics and Photonics nowadays for their low dissipative losses, which hold promise of high-efficiency devices, and unique optical properties, exhibiting strong magnetic-like optical resonances and associated scattering directionality, which renders them as excellent nanoantennas. Thereby a wealth of new or enhanced fundamental light-matter interactions at the nanoscale have been recently investigated using these HRI particles, either isolated or constituting new building blocks of more sophisticated arrangements, such as all-dielectric metasurfaces or metadevices, leading to enhanced directionality and Raman scattering, novel Brewster effects, zero-index materials, metalenses for miniaturized planar optics, sharp Fano resonances, and highly efficient sensing, etc. In addition, semiconductor nanostructures also offer longer excited-carrier lifetimes, may exhibit intrinsic non-linearities, and can be electrically doped and gated, or optically pumped, to realize subwavelength active optoelectronic devices.
