Abstract

A sensitive high-Tc superconducting bolometer has been fabricated with a YBCO thin film thermometer on a 20 microns thick sapphire substrate. Electrical measurements showed no noticeable film degradation after bolometer fabrication. Optical measurements gave a noise equivalent power of 5 x 10 to the -11th W/sq rt Hz 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.
