Abstract
Thin film Josephson junctions have been used as harmonic mixers to measure the frequency ofsubmillimetre wavelength laser lines. The highest frequency measured so far is 3.1THz. The need tomeasure frequencies in this spectral region arises from the measurement standards requirement to relateoptical and near optical frequency standards, used for frequency and length measurement, tomicrowave primary frequency standards. Information on submillimetre wave frequencies is alsoimportant to spectroscopists and other workers in what is likely to be an increasingly exploited partof the electromagnetic spectrum.
