Lasers for Nanophotonics

Nanophotonics or nano-optics is the study of the behavior of light on the nanometer scale, and of the interaction of nanometer-scale objects with light. It is a branch of optics, optical engineering, electrical engineering, and nanotechnology. It often (but not exclusively) involves metallic components, which can transport and focus light via surface plasmon polaritons.

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.’
