| 摘要 |
<p>A superconductive device is disclosed, which has specific characteristics of a generator and/or detector of sub-millimeter wavelength radiation, comprising a two-dimensional lateral array of mesas (column-shaped elements) each containing vertically stacked Josephson junctions on top of one another. This device is capable of covering the entire frequency range between the microwave and far infrared spectral regions, in a plurality of applications, where radiation emission and detection is involved. According to its various embodiments, thin columns (stacks) of Josephson junctions are monolithically built between superconducting electrical top and bottom contact layers. Mutually isolated segments cut out of the contact layers allow for optimization of circuit parameters such as impedance matching to load and maximizing the output power. External electronic control allows modulation of the radiation field and other operation modes of the device. The specification also describes special applications of the disclosed device. <IMAGE></p> |
