Lasers for nanophotonics
Plasmon Focusing on Single Crystalline Gold Platelets
In this applications note we read how the flexibility of the C-WAVE’s single frequency tunable wavelength can be utilized in nanophotonics experiments.
‘The manipulation of highly localized ﬁ elds 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.’
