摘要

We have studied the microwave properties of the Josephson junction array by measurement of Josephson self-radiation power and Shapiro-steps. The serial-parallel and parallel Josephson junction arrays were prepared with and without additional inductive coupling lines. The maximum detected power of 22 GHz from the serial-parallel array is about 25 pW and its peak point revealed a good quality of frequency-locking and exactly satisfied the Josephson voltage-frequency relationship. Although the parallel array has similar physical properties of average critical current and normal resistance of Josephson junctions to serial-parallel array, the maximum detected power is only about several tens of fW. The received power of serial-parallel array is higher than that of the parallel array for the same intensity of irradiation power. (C) 1998 Elsevier Science B.V. [References: 14]
