Microwave detector response of the Josephson junction arrays

G. A. Ovsyannikov, G.E. Babaian, V. N. Laptev +1 more

Microwave detector response ( eta ) for three types of superconducting structures-single edge-type Josephson junctions, arrays of series-connected junctions, and arrays of RF-series and DC parallel-connected junctions-were investigated in the frequency range 35-120 GHz. Experimental dependence of eta versus biasing voltage is mainly determined by the interaction of junctions in the array. The selective response, which means a narrow linewidth of Josephson radiation, is observed for the third type of superconducting structure in a small magnetic field changing the phase shift between closely-spaced junctions. These arrays have the advantage in coupling with the external microwave system.

Microwave Properties of Y1Ba2Cu3O7-x Step-Edge Josephson Junction Series Arrays

Shuichi Yoshikawa, Keiichi Yamaguchi, Kunihiko Hayashi +2 more

Effects on microwave detection of a series-connected Josephson junction array are examined. The series-connected 10 step-edge Josephson junctions (10-SEJJs) are fabricated by Y1Ba2Cu3O7- x thin films on MgO substrates. Their responsivities as microwave broad-band detectors are evaluated by constructing microstrip circuits for measuring transmission and return power. 948 V/W is obtained at 17 K. This value is several times greater than 139 V/W of a single SEJJ at 17 K. Additionally, the return power from 10-SEJJs is less than that from the single SEJJ, as the bias current or the temperature increases. The small return power is attributed to the increase in the normal resistance of the SEJJ.

Detected power and linewidth of Josephson self-radiation from frequency-locked and microwave-coupled arrays in a waveguide detection system

Insang Song, Kwang‐Yong Kang, Gwangseo Park

Frequency-locked and microwave-coupled arrays of high- superconducting Josephson junctions have been developed. The Josephson junctions were prepared on bicrystal MgO substrates using a pulsed laser ablation method. The maximum detected power of Josephson self-radiation, which is directly detected by a superheterodyne receiver with a central frequency of 22 GHz, from the arrays was enhanced with increasing number of Josephson junctions. The Josephson self-radiation properties of the arrays revealed a good quality of frequency locking and exactly satisfied the Josephson voltage-frequency relationship. A narrower linewidth of the Josephson self-radiation was obtained by increasing the number of Josephson junctions in the array.
