To prove their concept, the researchers used a three - dimensional, microwave -
scale photonic crystal constructed from layered alumina rods and containing a full bandgap — a wavelength range in which electromagnetic waves can not transmit.

Pete Vukusic and Ian Hooper of Exeter University in England studied the colored parts of the swallowtail's wings and found that the
scales that comprised them contain
photonic crystals whose atoms are spaced so precisely that only certain wavelengths of light can pass through.
«This technology allows for high resolution, high precision, fast speed, large
scale preparation of
photonic crystal patterns,» says Bai.
