Abstract

We report on a far-infrared Fabry-Perot resonator consisting of two high T(c) YBa2Cu3O7-delta films on silicon plates. By pulsed laser deposition we prepared on the (100) silicon plates c-axis oriented epitaxial films (thickness approximately 30 nm) with zero resistance at 88.5 K. We demonstrate operation of the resonator in the terahertz frequency range, up to approximately 20 THz. At low temperature a high peak transmissivity (between 0.2 and 0.6) and a finesse of the order of 10 have been reached.
