Nanophotonics and plasmonics
Nanophotonics explores the light-matter interaction phenomena at small scales: the characteristic
dimensions of the structures under study are in the nanometer range. At these tiny sizes, visible light
behaves in a very different way than it does in the macroscopic regime, allowing exciting phenomena to
One of the most interesting marvels arising from this strange behavior is the combination of light waves
with the conduction electrons in the nanoscale materials. When these collective effects appear, the electric
fields get shrunk to very small regions in space, where the field intensity gets strongly enhanced. The
resulting phenomenon of this combination is called a plasmon, and these appealing properties gave
rise thirty years ago to the conception of plasmonics: one of the most prolific fields in
nanophotonics at the time.
Nowadays the efforts in the plasmonics community involve, among other trends, further miniaturization of
the plasmonic devices, as well as the search for actual applications for plasmons outside the fundamental
research environment. My current research trend involves fulfilling these two aims.
