Optical Properties of New Type of Superconductor-Semiconductor Metamaterial Photonic Crystals

Research Abstract

Based on the fundamentals of the characteristic matrix method, we theoretically investigate the optical properties of one-dimensional superconductor metamaterial photonic crystals. The photonic crystals are composed of a superconductor layer and two semiconductor metamaterial layers of In0.53Ga0.47As with different doping densities. The numerical results show negative values in permittivity of the metamaterial layer along a broad band of the incident radiation. The negative values show a significant effect on the optical properties of the present structure. Moreover, the optical properties of our design can be controlled by different parameters such as thicknesses of the layers, the operating temperature and the doping density. Our results may be suitable for different applications in the optical community.
