Coherent control of plasmonic nanoantennas using optical eigenmodes

In a paper published in Nature Scientific Report we show how to couple light to subwavelenght plasmonic features using the principle of optical eigenmodes. This technique can be used also in presence of large optical aberrations and allow to selectively couple light to nanofeatures in a crowded region, with minimal crosstalk.

In the picture we show a SEM picture of a typical sample (gold nanoantennas on glass) that we fabricated to test the technique.
