Plasmon Focusing on Single Crystalline Gold Platelets using C-WAVE


The manipulation of highly localized fields of surface plasmon polaritons (SPPs)
forms the backbone for a vast fi eld of applications. We investigate the SPPs excited
on a single crystalline gold nanoplatelet milled with a plasmonic lens structure
using a scattering type scanning near fi eld optical microscope. SPPs are excited
at different wavelengths in the visible regime employing a new tunable continuous
wave source. Wave vector selection of the SPPs by the gold structures corresponded
well with the numerically calculated dispersion relationship.
