Emission of radiation from square arrays of stacked Josephson junctions
Giovanni Filatrella, B. L. Straughn, Paola Barbara
We propose a design for two-dimensional arrays of stacked Josephson junctions and study their properties as coherent sources of radiation in the mm and sub-mm wavelength range. This design can be implemented by using either mesas of intrinsic Josephson junctions, from crystals of high TC superconductors, or artificial stacks of low TC junctions. We outline a possible Nb/AlOx/Nb trilayer fabrication process for such devices. Our model for the dynamics of the system predicts the range of parameters over which the junctions synchronize.
