We report the experimental demonstration of the linear kinetic-inductive photoresponse of thin-
film YBa2Cu3O7- 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.
