How infrared light can be captured by graphene nanostructures

Researchers from CIC nanoGUNE, in collaboration with ICFO and Graphenea, have demonstrated how infrared light can be captured by nanostructures made of graphene. This happens when light couples to charge oscillations in the graphene. The resulting mixture of light and charge oscillations,called plasmon, can be squeezed into record-small volumes millions of times smaller than in conventional dielectric optical cavities. This process has been visualized by the researchers for the first time with t
