We report on experiments showing that high-T(c) superconductors are well suitable for constructing of high-quality far-infrared Fabry-Perot interference filters in the terahertz frequency range. In an interference filter we use two plane-parallel MgO plates with YBa2Cu3O7 thin films as partly transparent reflectors on adjacent surfaces. For the first-order main resonances adjusted to frequencies around 2 THz a quality factor of approximately 200 and a peak-transmissivity of approximately 0.5 have been reached. Study of the filters with YBa2Cu3O7 films of different thickness indicate the possibility of reaching still higher selectivity. An analysis of the filter characteristics delivered the dynamical conductivity of the high-T(c) films.
