Recent theory for scattering lattices with spatially distributed loss and gain point at the potential for topological and pseudochiral bandstructure physics. At the same time, these systems are quite different from true tight-binding systems, owing to long-range dipole dipole coupling, and diffraction channels. We study plasmonic realisations in a femtosecond pump probe set up that provides single-shot imaging, k-space mapping and photonic band structure mapping I will present experiments on diffractive and significantly sub-diffractive amplifying and lasing nanophotonic lattices.
