Abstract
The natural sedimentation method combining with the isothermal heating evaporation induced self-assembly is presented to fabricate three-dimensional (3D) colloidal crystals in the curved cavity of the fiber end face. A-50 \mu m-deep cavity is etched by hydrofluoric acid. The colloidal crystals are characterized by optical and scanning electron microscopy. A 1380-nm stop band is observed by measuring their transmission spectra at normal incidence by an optical spectrum analyzer (OSA).
