Abstract

SiO 2/air three-dimensional (3D) periodic structures were fabricated by removing Si layers partially from Si/SiO 2 3D photonic crystals (PhCs) formed by using autocloning. CdS/SiO 2 3D periodic structures were formed by introducing CdS into the SiO 2/air structures by the TEA method and photoluminescence (PL) was observed from the introduced CdS. TiO 2/air/CdS two-dimensional (2D) PhCs were also fabricated by introducing CdS into the voids of TiO 2/air 2D periodic structures, in which SiO 2 layers were partially etched out from TiO 2/SiO 2 2D PhCs fabricated by using autocloning. PL radiating normal to the surface was measured and large polarization dependence was observed.
