Description

We have measured the ac Josephson effect in Nb point contacts at 604 GHz (496 μm). We find the coupling of the far-infrared radiation to the point contact to depend in a simple manner on the resistance of the contact. The behavior of the high-resistance point contacts (50< or =R< or =200 Ω) is very reproducible, allowing a quantitative comparison of the data to the frequency-dependent Werthamer theory. We also account for the effects of noise and heating and compare these to Tinkham's heating theory
