Abstract

Three-dimensional photonic crystals (PhCs) provide materials for the production of highly efficient light sources. In this respect, the channelling and suppression of the spontaneous emission (SE) due to the anisotropic nature of the photonic band gap (PBG), and band-edge stimulated emission, have been demonstrated. Various attempts have been reported on light emission in the telecommunication and visible wavelength ranges. For light emission in the ultraviolet region, ZnO stands out for its wide electronic band gap ~3.4eV and direct band-to-band transition.
