Abstract:

Based on the Mie scattering theory and the low density approximation, the photonic localization of opal photonic crystal constituted by Ge was studied. The influence laws between the incidence wavelength, the size of the scatterer, the refractive index of medium and localization parameters were numerically revealed. The results show that the ideal photonic localization phenomenon appears in middle infrared band (3um~12um) under the conditions of the scatterer’ density of 10% and the relative refractive index greater than 3.8; with the increase of incidence wavelength, the localization area shifts to geater scatterer’s radius, and the localization parameter decreases. Meanwhile, with the increase of medium’s refractive index, the localization phenomena become weak.
