Non-absorbing, periodic, strongly scattering dielectric structures remove the path for propagation of light of certain frequencies, thus, creating a photonic band gap are known as Photonic Band Gap Materials, PBGM Numerous methods are available to fabricate a 3-D PBGM, the photonic analog of electronic semi conductor. The method described involves the use of a silica template, infiltration of high refractive index or other materials of interest and removal of template. Template formation involves synthesis of monodispersed silica spheres followed by the self-assembly or electrophoretic deposition into close packed Face Centered Cubic (FCC) structure.
