Welcome to the Nano-Optics website.

What we do, in four images: 

Topography	Magnitude |E|
Phase φ = arg(E(t))	Instantaneous field strength ℜ{E(t)}

We measure plasmonic nano-structures, here gold nano-discs. An atomic force microscope records the topography, while simultaneously our homebuilt apertureless scanning nearfield optical microscope measures the magnitude and phase of the plasmonic eigenmodes of the structures, as they are excited by laser radiation.
