Abstract :
The natural sedimentation method combined with the isothermal heating evaporation induced self-assembly is presented to fabricate three-dimensional colloidal crystals in the curved cavity of the fiber end face, which was etched by hydrofluoric acid. The colloidal crystals is characterized by scanning electron microscopy, shown to be face centered-cubic structure. A 1380 nm photonic band gap is observed by measuring their transmission spectra at normal incidence by optical spectrum analyzer.
