Abstract
We report a numerical study of the effect of material dispersion on the omnidirectional reflectors (ODR) properties in the case of one-dimensional photonic crystal structures consisting of alternate layers of zinc oxide as material of high refractive index and SiO2 as material of low refractive index. The interplay of dispersion and structural parameters on the ODR properties of the structure of interest has been analyzed. Taking into account the material dispersion properties, shift in the wavelength range for ODR from (1079  −  1158  nm) to (1133  −  1103  nm) is observed. This shows the narrowing of the bandwidth for ODR from 79 to 30 nm as a result of material dispersion. The wavelength range of interest is close to optical communication wavelengths and is useful in many optical device applications.
