Manipulating Light in Arrays of Nanoscale Holes and Pyramids
Abstract:
This talk focuses on how the shape of nanostructures can control light on the nanometer scale. Two different systems will be discussed: (i) metallic films of nanohole arrays and (ii) arrays of pyramidal nanoparticles. We will describe an innovative fabrication scheme for preparing large-area, free-standing films of nanoscale holes. When investigated in the near-field, these films support surface plasmon polariton standing wave patterns whose wavelength and polarization can be controlled. These nanohole arrays also exhibit enhanced optical transmission. Finally, we will discuss the manipulation, characterization, and functionalization of anisotropic metallic pyramidal shells.
