ABSTRACT
We provide a demonstration of ultrafast sampling measurements using the photokinetic effect in high-T[SUBc] superconductors to observe fast electrical signals in and rf resonator structure. We observe direct mixing of an applied optical sampling pulse with an ultrafast electrical signal capacitatively coupled to the sampling microbridge. The structures used here are 10 μm wide bridges lithographically defined in thin Tl[SUB2]Ba[SUB2]CaCu[SUB2]O[SUB10] films. The time resolution and sensitivity of the technique are evaluated and the effects of bias currents on signal strengths are explored.
