摘　　要：研究了嵌入Fabry-Perot谐振腔的高温超导双晶约瑟夫森结阵列毫米波相干辐射的实验结果.相干辐射是通过约瑟夫森结阵列与基片(作为一个介质谐振器)和Fabry-Perot(FP)谐振器的共同作用实现的.由166个高温超导双晶约瑟夫森结串联阵列在77K温度下产生的相干辐射,辐射峰的中心频率为75.84GHz,功率大约为10pW.The experimental results of mm-wave coherent emission from a high temperature superconducting bicrystal Josephson junction array embedded in a Fabry-Perot resonator are reported in this paper. The mm-wave coherent emission from the series junction array results from the interaction of the junctions with the substrate serving as the dielectric resonator as well as the Fabry-Perot resonator. The central frequency of emission of a Josephson junction array containing 166 bicrystal junctions was 75. 84 GHz,and the detected emission power was about 10 pW at 77 K.
