Abstract
An optical security feature has pixels with faceted microstructures supporting nano-patterned optical filters. Each of the pixels includes a substrate and a nanostructure. The substrate is configured to emit light of at least a first wavelength and a second wavelength different than the first wavelength. The microstructure includes a first facet, a second facet non-parallel to the first facet, a first nano-patterned optical filter disposed on the first facet, and a second nano-patterned optical filter disposed on the second facet. The first nano-patterned optical filter includes a first stopband that includes the first wavelength and excludes the second wavelength. The second nano-patterned optical filter includes a second stopband that includes the second wavelength and excludes the first wavelength. For each pixel, the first nano-patterned optical filter inhibits emission of light at the first wavelength from the pixel via the first facet.
