Abstract
We report on the application of high-Tc superconductors as reflectors for far-infrared Fabry-Perot resonators. At low temperatures and frequencies smaller than the superconducting gap frequency the optical properties of YBa2Cu3O7-δ are mainly determined by inductive currents. Therefore YBa2Cu3O7-δ thin films on MgO, which is transparent in the far-infrared, are suitable for Fabry- Perot resonators with high peak-transmissivity. We report on a resonator with first order resonance at a frequency of 80 cm-1, a quality factor of 55 and a peak transmissivity of 0.16.
