Photo-reversible tunable photonic crystals were fabricated by the infiltration of photochromic dyes into the voids of opal films. The enhanced changes in refractive indices due to the resonance effect of the dyes regulated the stop bands of the dyed opals. It was found that all changes can be reversibly tuned back and forth giving these photonic crystals excellent potential for applications in optical transfer devices.
