title: Corrugated metallodielectric superlattices via release-rollup assembly.
abstract: A 'release-rollup' assembly (RRA) technique is described that yields corrugated metallodielectric superlattices. Bilayers of polymer/Au cast onto diffraction gratings are released and rolled into multilayers with registration of the stacked corrugations across mm-scales. Optical imaging reveals Moiré fringes with reflection spectra that track the bilayer thickness due to mis-stacking. Angular-resolved spectra show spectrally-modulated diffraction opposite to that of the metallic stop-bands, but which agrees with a simple model. This scalable fabrication strategy is thus widely exploitable for laterally patterned metamaterials and optical superlattices.
