[EurekAlert]The Photonic Beetle

Researchers have been unable to build an ideal “photonic crystal†to manipulate visible light, impeding the dream of ultrafast optical computers. But now, University of Utah chemists have discovered that nature already has designed photonic crystals with the ideal, diamond-like structure: They are found in the shimmering, iridescent green scales of a beetle from Brazil.
Quote:
The ideal photonic crystal – dubbed the “champion†crystal – was described by scientists elsewhere in 1990. They showed that the optimal photonic crystal – one that could manipulate light most efficiently – would have the same crystal structure as the lattice of carbon atoms in diamond. Diamonds cannot be used as photonic crystals because their atoms are packed too tightly together to manipulate visible light.

When made from an appropriate material, a diamond-like structure would create a large “photonic bandgap,†meaning the crystalline structure prevents the propagation of light of a certain range of wavelengths. Materials with such bandgaps are necessary if researchers are to engineer optical circuits that can manipulate visible light.

Does this mean we will hunt these beetles for their crystals, but in exchange will get ultra-fast computers?

I'm surprised something this intriguing generates less interest than the recent slew of piracy threads... Just read through the article @ wired, can't wait for optical computing to become a reality. Great find OP, wish I had seen it sooner!
