Abstract :
We report on the successful fabrication of a working three-dimensional (3D) crystal operating at optical wavelength λ. The minimum feature size of the 3D structure is 180 nm. The 3D crystal is free from defects over the entire 6-inch silicon wafer and has an absolute photonic bandgap (PBG) centered at λ~1.6 μm. Our data provides the first conclusive evidence for the existence of a complete 3D PBG in optical λ. This development will pave the way to tinier, cheaper, more effective waveguides, optical switches and lasers
