Abstract:
Prototypes of the design of Josephson traveling-wave parametric amplifier based on aluminum superconductor–insulator–superconductor junctions in the form of direct-current SQUIDs included in central conductor of coplanar line are developed, fabricated, and investigated. Three manufacturing methods for the fabrication of such devices are tested: two of them using shadow evaporation and one using magnetron sputtering and direct electron-beam lithography. Current–voltage characteristics of the junctions are measured at 0.3 K. A cryogenic setup for the measurement of spectral characteristics of such amplifier containing cold semiconductor amplifier with circulator and cooled attenuators of the channels of input signal and pump is developed. The absorption spectrum of coplanar directional coupler with a quarter-wave resonator dedicated for measurements of short chains from one to 27 SQUIDs is measured.
The work was supported by the State Assignment of the Institute of Radio Engineering and Electronics of the Russian Academy of Sciences (no. 030-2019-0003) and the State Assignment of the Institute of Applied Physics of the Russian Academy of Sciences. Fabrication, development, and investigation of the specimens were supported by the Russian Science Foundation grant no. 21-42-04421 based on a unique scientific setup (UNU no. 352529). Development of individual elements of the technology of THz detectors was performed by A. Gunbina in the Institute of Applied Physics of the Russian Academy of Sciences within the Russian Science Foundation project no. 19-19-00499.
