博士 === 國立交通大學 === 電子物理系所 === 98 === It has been developed for periods of time to research the optical properties of periodic multilayer structures. In the past years, the photonic band gap structure were mainly fabricated by using the usual dielectrics, semiconductor and metal as well. Recently, the new materials like superconductors and the metamaterials have been developed very soon. The main purpose of our research work is to study the optical properties of the periodic multilayer structures with superconductors and metamaterials. The discussions of photonic band structure have been made and we attempt to seek some unusual phenomena and the special property for application. The photonic band structure in the transversal electric mode for a one-dimensional superconductor-dielectric superlattice is theoretically calculated. By using the two-fluid model of superconductors, the band structure is shown be strongly consistent with the transmittance spectrum. Next, we investigate the optical properties of the annular Bragg reflectors containing superconductors and metamaterials. By using the transfer matrix method for the cylindrical waves developed by Kaliteevski et al., we calculate the reflectance spectra for the annular Bragg reflectors. Numerical results show that the optical properties of the annular Bragg reflectors are fundamentally different from those of the planar Bragg reflector with azimuthal mode number . The special results suggest that the annular Bragg reflectors could be used to design a narrowband transmission filter or an annular resonator without introducing any physical defect layer in the structure.
