Study of Josephson-effect arrays as sources at 1 THz. Final report, Aug 86-Jan 90

Technical Report ·
OSTI ID:5475286
Techniques have been developed and tested for coupling 40 junction arrays of Josephson effect oscillators to achieve coherent operation in the submillimeter wave range. Arrays have been fabricated using both lead alloy and niobium trilayer technology. Coherent operation has been demonstrated between 150 GHz and 500 GHz. The maximum power was developed at 400 GHz where 7 microwatts was delivered to a 20 Ohm on-chip load.
