Visible and Infra-red Resonant Light Scattering from Plasmonic Nanowire Architecture
Abstract
The objective of this proposal is to study angle-dependent scattering from individual plasmonic nanowire architectures placed on a dielectric substrate. We will utilize Fourier-plane optical microscopy method to resolve the angular scattering as a function of spherical co-ordinates: azimuthal and polar angles. Our measurements will be corroborated by numerical simulations based on finite difference time domain and finite element analysis. Using the proposed method we will be able to measure broadband (visible and infra-red) scattering from a single plasmonic nanowire spanning polar angles from -70 degrees to +70 degrees, and azimuthal angles from 0 to 360 degrees. The implications of this study will have direct consequence in understanding the directivity and local field enhancement of plasmonic nanowires based optical antennas, and can be further harnessed in applications such as nanoscale sources of light and heat. This study also has direct implication in probing scattering invisibility and its spectral dependence.
