Thumbnail image of graphical abstract

Butterfly-mimetic photonic nanostructures are fabricated by shearing large arrays of nanometer-scale structures, prepatterned using nanoimprint lithography. The overlapping domino-like structures generate a tunable bright iridescent effect similar to that found in natural butterfly wings (see image).
