Abstract

Research is in progress to develop a local oscillator at 1 THz based on the Josephson effect in superconductors. In general, it is necessary to use arrays of Josephson junctions to obtain the required power, linewidth and impedance levels from such sources. The criteria for properly phase-locking the junctions in such an array, distributed over many wavelengths, are discussed along with the projected performance at 1 THz. A power level of 1μW at 300GHz has been demonstrated using these designs.
