Abstract
A comparative study of enhancement of omnidirectional high-reflection wavelength range in one-dimensional ternary structured photonic crystals (PCs) was carried out. The PCs investigated are of the dielectric-birefringent type and the dielectric-metallic type. These were compared with a 1D all-dielectric ternary PC investigated earlier by us. The dielectric-birefringent PC gives a larger range enhancement as compared to the all-dielectric one, together with a reduction in the number of periods of the structure. Maximum range enhancement is obtained in the metallodielectric ternary PC, with a further reduction in size, as only six layers need to be deposited in this case. This implies easier fabrication methods and lower costs.
