An international team of researchers (Finland, Germany) has shown that carefully structured light and matching arrangements of metal nanostructures (plasmonic oligomers) can be combined to alter the properties of the generated light at the nanometer scale. They designed and fabricated assemblies of gold nanorods with well-defined dimensions and orientations such that their overall size matches the size of a focused laser beam, i.e., about 1 micron. The results show in general how important it is to tailor the incident optical beam to couple light efficiently into complex nanostructures. Their results will be useful in the design and implementation of new kinds of optical components and characterization techniques that utilize unconventional optical fields… read more.
