Researchers at the University of Stuttgart measured for the
first time optical near-field intensities of three-dimensional nanoantennas.
The team of Prof. Harald Giessen at the 4th Physics Institute achieved those
results with a novel scheme of nanospectroscopy and published their paper in
the journal “Nature Communications”.*) Their method gives new insight into
light-matter coupling at the nanoscale and allows precise measurement of
enhanced optical near-field intensities generated by optical antennas. This
technique can facilitate the engineering of future sensing platforms with
extremely high sensitivity.
