PHASE-LOCKED ONE-DIMENSIONAL AND 2-DIMENSIONAL JOSEPHSON-JUNCTION ARRAYS AS MILLIMETER AND SUBMILLIMETER-WAVE GENERATORS

The results of numerical simulations of phase-locked 1D and 2D Josephs on-junction arrays are reported. It is shown that the multi-junction s tructures with non-local junction interaction provide phase-locked osc illation state within wide critical current margins Delta I-c up to 40 ..50%. The effective non-local interaction in 2D structure based on 4- junction interferometer cell can be provided by the regular single flu x quantum array flow across it. The wide tolerable spread in Delta I-c allows to realize both (i) phase-locked 2D high-T-c Josephson-junctio n array with the oscillation frequency F close to characteristic value F-c and (ii) based on Nb tunnel Josephson-junction technology 1D arra y with the voltage-controlled phase-locked oscillation frequency withi n wide frequency band from 0.4F(c) to 1.2F(c).
