Abstract: The mm-wave irradiation characteristics of Tl2Ba2CaCu2O8 (Tl-2212),a high temperature superconducting thin film bicrystalJosephson junction embedded in a hemispherical Fabry-Perot resonator,is studied.The optimized coupling between Josephson junction and applied microwave is achieved by subtle adjustment of the various factors of resonator.5 orders distinct Shapiro steps are observed.The radiation property of serial array consistingof 667 bicrystal Josephson junctions is measured and the radiation power is approximately 6 pW at 78.7 GHz center frequency.

Key words: high temperature superconducting thin film, Fabry-Perot resonator, Josephson junction, Shapiro step
