Abstract
Plasmon antenna lattices enjoy a long history in the domain of fluorescence control, SERS, sensing and plasmon lasers, due to the combination of high Q and strong field enhancement, by virtue of diffractive resonances. Recent theory for honeycomb, Kagomé and distributed loss and gain lattices point at the potential for topological and pseudochiral bandstructure physics. For this regime, sub-diffractive periodicities are particularly interesting, pushing the array bandstructure beyond the light line and in a regime where plasmon antennas interact strongly. I will present experiments that access this band structure on basis of far-field reflective, fluorescence, and nonlinear Fourier microscopy.
