Based on periodic anodization of aluminum, photonic crystals with photonic band gaps in the range of 625 and 740 nm were fabricated. Structural characteristic of prepared photonic crystal such as lattice constant can be well controlled by applying different voltage shapes. Optical measurement revealed that position of band gap depends on the lattice constant and consequently, the Bragg condition is satisfied. It was also found that the transmission light in photonic band gaps of the samples is lower than 2%.
