Abstract:
This chapter looks at how optical microstructures in butterfly scales produce colour, as well as structural black and white. Butterflies contain some of the most diverse optical microstructures nature has to offer. The most interesting and complex of these are three-dimensional photonic crystals. The refractive index contrasts available ...
