As the periodicity of resulting array, grid pattern, shape of the openings and the size of the openings can be varied by varying different exposure parameters this method can lead to fabricating two - dimensional photonic crystal [4]. Finally the periodic structure should be fabricated in more proper material, which can be dielectric one (glass) and only photonic bandgap could be observed then, or photonic crystal can be made of electronic semiconductor material leading to both electronic bandgap and photonic bandgap utilisation.
