| description | Terahertz unidirectional resonant absorption in a finite one-dimensional defective superconducting photonic crystal is theoretically investigated. We consider an asymmetric photonic crystal (AB)<italic><sup>N</sup></italic>D(BA) <italic><sup>M</sup></italic>, where A is a dielectric, B is a superconductor, D is the dielectric defect, and <italic> N</italic>, <italic>M</italic> are the stack numbers, respectively. At <inline-formula><tex-math notation="LaTeX">$N \ne M$</tex-math></inline-formula>, it is found that the resonant absorption for the structure exhibits the unidirectional property. The unidirectional resonant absorption points increase as the difference between <italic>N </italic> and <italic>M</italic> increases. We also investigate the unidirectional property as a function of angle of incidence. The results show that the unidirectional absorption is nearly independent of the polarization at a given angle of incidence. The proposed structure can be used to design a polarization-independent optical device which may be technically used in superconducting photonics. |
