摘要

The natural sedimentation method combining with the isothermal heating evaporation induced selfassembly is presented to fabricate three-dimensional(3D) colloidal crystals in the curved cavity of the fiber end face.A~50-μm-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).
