Yablonovite is a photonic crystal structure that has an

inverse cylindrical hole Inverse or invert may refer to: Science and mathematics * Inverse (logic), a type of conditional sentence which is an immediate inference made from another conditional sentence * Additive inverse (negation), the inverse of a number that, when ad ...

s arranged in a

diamond lattice The diamond cubic crystal structure is a repeating pattern of 8 atoms that certain materials may adopt as they solidify. While the first known example was diamond, other elements in group 14 also adopt this structure, including α-tin, the sem ...

. It was the first 3D photonic crystal to be fabricated with a complete

photonic bandgap A photonic crystal is an optical nanostructure in which the refractive index changes periodically. This affects the propagation of light in the same way that the structure of natural crystals gives rise to X-ray diffraction and that the atomic ...

. It was created in 1991 by Eli Yablonovitch and his team.Yablonovitch, El
"Photonic Crystals: Semiconductors of Light"
''Scientific American'', December 2001, accessed February 22, 2011. The structure that Yablonovitch was able to produce involved drilling a triangular array of cylindrical holes in layers of transparent material, where the holes of each layer are placed on top of the remaining material in the layer below, the structure repeats every 4 layers, and was modeled after an inverse diamond structure.
