First evidence for 1−mm wavelength parametric amplification in a Josephson junction microwave source

Our observation of 1−mm wavelength radiation generated in a cavity containing a Josephson junction provides evidence for a negative effective microwave resistance in the Josephson junction, and for parametric amplification in the reflection mode by the Josephson junction. These parametric oscillatio...
