Superlattice Surface Lattice Resonances in Plasmonic Nanoparticle Arrays with Patterned Dielectrics

This paper describes how two-dimensional plasmonic nanoparticle latticescovered with microscale arrays of dielectric patches can show superlattice surface latticeresonances (SLRs). These optical resonances originate from multiscale diffractive coupling thatcan be controlled by the periodicity and size of the patterned dielectrics. The features in theoptical dispersion diagram are similar to those of index-matched microscale arrays of metalnanoparticle lattices, having the same lateral dimensions as the dielectric patches. With anincrease in nanoparticle size, superlattice SLRs can also support quadrupole excitations withdistinct dispersion diagrams. The tunable optical band structure enabled by patterned dielectricson plasmonic nanoparticle arrays offers prospects for enhanced nonlinear optics, nanoscalelasing, and engineered parity-time symmetries.
