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.’

Tunable lasers

C-WAVE is the tunable laser light source for continuous-wave (cw) emission in the visible and near-infrared wavelength range for demanding applications as in atomic physics or quantum optics.
