Quasi-optical Josephson-junction oscillator arrays

IEEE transactions on applied superconductivity
Preserved Fulltext
Josephson junctions are natural voltage-controlled oscillators capable of generating submillimeter-wavelength radiation, but a single junction usually can produce only 100 nW of power and often has a broad spectral linewidth. We are investigating twodimensional quasi-optical power combining arrays of 103 and lo4 NbN/MgO/NbN and Nb/Al-AIOJNb junction to overcome these limitations. The junctions are DC biased in parallel and are distributed along interdigitated lines. The arrays couple to a
