DESCRIPTION
Manipulating nanoscale light in scanning tunneling microscope junctions is attained by nanofabrication of gold tips using a focused ion beam technique. Researchers at Fritz-Haber Institute, Berlin, Germany, demonstrated that a spectrum of 'nanolight' in a nanoscale plasmonic junction can be modulated with plasmonic Fabry-Pérot tips. Precise control of nanolight is of key relevance to nanoscale imaging and spectroscopy to investigate structure, dynamics, optoelectronic properties of nanomaterials and single molecules.
