Abstract

Anomalous far-infrared monochromatic transmission through a lattice of Abrikosov vortices in a type-II superconducting film is found and reported. The transmitted frequency corresponds to the photonic mode localized by the defects of the Abrikosov lattice. These defects are formed by extra vortices placed out of the nodes of the ideal Abrikosov lattice. The extra vortices can be pinned by crystal lattice defects of a superconductor. The corresponding frequency is studied as a function of magnetic field and temperature in the framework of the Dirac-type two-band model. While our approach is valid for all type-II superconductors, the specific calculations have been performed for the YBa2Cu3O7−δ. The control of the transmitted frequency by varying the magnetic field and/or temperature is analyzed. It is suggested that the found anomalously transmitted localized mode can be utilized in the far-infrared monochromatic filters.
