Growth of All-Metal 3D Photonic Crystals With a Large Infrared Band Gap. The tungsten 3D photonic crystal was made by selectively removing Si from already fabricated polysilicon/SiO2 structures, and back-filling the resulting mould with chemical vapour deposited (CVD) tungsten.

Growth of All-Metal 3D Photonic Crystals With a Large Infrared Band Gap The tungsten 3D photonic crystal was made by selectively removing Si from already fabricated polysilicon/SiO2 structures, and back-filling the resulting mould with chemical vapour deposited (CVD) tungsten. This method could be extended to create almost any 3D single-crystal metallic photonic crystal at infrared wavelengths; such photonic crystals have not previously been achievable. J.G. Fleming, S.
