Abstract
We report on the fabrication and characterization of optical detectors made from 100 A thick high Tc superconducting films. A microbridge detector showed response to 50 ps optical pulses with 1 ns rise time. A nonbolometric vortex depairing mechanism at the Kosterlitz-Thouless transition temperature was observed. A detector pattern utilizing a 1.6 micron wide Meander-line showed approximately equal response amplitude at a lower bias current. The response mechanism was mainly bolometric but for 5 ns pulses vortex depairing was observed.
