Abstract

In this paper, we focus on a theoretical study at visible wavelengths of band gap structures in ZnO as a function of the geometry and the features of the grating. Both 2D and 3D photonic crystals are considered. The frequency was also analyzed via this work by computing the resonant mode in twodimensional photonic crystal cavities. Results of photonic band gap for both transverse magnetic (TM) and transverse electric (TE) polarizations show the existence of a complete 2D photonic band gap (PBG) for an hexagonal structure with a ratio r/a (radius of the holes over the period of the structure) about of 0.42. For 3D PBG, the face centred cubic (fcc) structure allows the obtaining of a PBG with a ratio r/a equal to 0.23 highlighting the great potential of ZnO as a promising material for photonic crystals applications.
