Numerical modelling of scattering properties of tunable hybrid nanostructures

摘要

Developments of optical data storage systems tend to arouse scientific interest as such systems can potentially provide a higher storage capacity compared to existing technologies. In this work, we are introducing results of optical properties numerical modeling of tunable hybrid metal-dielectric nanoantennas whose geometric parameters and shape can be modified via fs-laser induced melting. We find geometries of the system which can provide distinct reconfiguration of scattering and absorption spectrum in the visible in dependence of the gold component shape. The results obtained in this work can be used to develop a system for optical information recording with high density.
