Metallic nanostructures are able to concentrate light into volumes far below the diffraction limit. Here we show, by accurate scattering calculations, that nanostructures obtained from thin films of J-aggregate dyes, concentrate the electromagnetic field at optical frequencies. Moreover, in contrast to metal nanoparticles, these molecular aggregates display highly attractive nonlinear optical properties that can be exploited for the realization of ultracompact devices for switching light by light on the nanoscale without the need of additional nonlinear materials. These results open new perspectives in plasmonic based nanophotonics.
