Optical Nonlinearity: A Novel Hierarchical Nanostructure for Enhanced Optical Nonlinearity Based on Scattering Mechanism (Small 39/2020)
Source abstract
Abstract
By using sequential ion implantation, Feng Chen and co-workers implement a three-layer hierarchical nanostructure in LiNbO3 crystal with embedded plasmonic Cu and Ag nanoparticles in article number 2003172. Under excitation of a femtosecond laser, the ultrafast dynamic response of the nanostructure is tailored through the scattering mechanism at the interface between Cu and Ag nanoparticle layers. The optical nonlinearity is enhanced owing to the synergistic effect of the plasmonic nanoparticles, which suggests potential applications in nonlinear photonic devices.
