Ultrafast linear kinetic inductive photoresponse of YBa2Cu3O7−δ meander-line structures by photoimpedance measurements

Abstract

We report the experimental demonstration of the linear kinetic-inductive photoresponse of thin-film YBa2Cu3O7−δ meander line structures, where the photoresponse amplitude, full-width-half-maximum, and rise time are bilinear in the incident optical power and bias current. This bilinear behavior reveals a trade-off between obtaining high responsivity and high speed photodetection. We also report a rise time as short as 29 ps in our photoimpedance measurements.
