A sensitive high {Tc} superconducting bolometer has been fabricated with a YBCO thin film thermometer on a 20 {mu}m thick sapphire substrate. Electrical measurements showed no noticeable film degradation after bolometer fabrication. Optical measurements gave a noise equivalent power of 5{center dot}10{sup {minus}11} W/Hz {sup {1/2}} at 10 Hz and a responsivity of 22 V/W. This performance is comparable to that of the very best pyroelectric detectors. Significant improvement appears possible. 4 refs., 3 figs.
