The first direct observation of the parametrically generated half-harmonic voltage in a Josephson tunnel junction is reported. A microwave signal at f=17.25 GHz is applied to the junction dc current biased at zero voltage such that the Josephson plasma resonance f/subp/=f/2. Under these conditions a large-amplitude microwave signal is emitted at f/subp/ provided the input power exceeds a threshold value. The results are compared to existing theory. (AIP)
