We discuss the tailoring of linear chiroptical effects in three-dimensional plasmonic nanohelices by means of challenging technological nanoscaling approaches, allowing the operation of this metamaterial in the optical frequency range. The growth dynamics involved in focused ion and electron beam-induced deposition have been extensively studied and targeted to the realization of complex 3D structures where intrinsic chirality and spatial anisotropy can be controlled at the nanoscale level, toward miniaturized chiral photonics for application in optoelectronics and biological detection.

Abstract
We discuss the tailoring of linear chiroptical effects in three-dimensional plasmonic nanohelices by means of challenging technological nanoscaling approaches, allowing the operation of this metamaterial in the optical frequency range. The growth dynamics involved in focused ion and electron beam-induced deposition have been extensively studied and targeted to the realization of complex 3D structures where intrinsic chirality and spatial anisotropy can be controlled at the nanoscale level, toward miniaturized chiral photonics for application in optoelectronics and biological detection.File in questo prodotto:
