This paper reports on a sensitive high T{sub c} superconducting bolometer fabricated on a 20{mu}m thick sapphire substrate with a YBCO thin film transition edge thermometer. Optical measurements with a He-Ne laser gave a noise equivalent power of 2.4 {center dot} 10{sup {minus}11} W/Hz{sup 1/2} at 10 Hz and a responsivity of 17 V/W in good agreement with electrical bolometer measurements. Gold black smoke was then deposited on the back side of the assembled bolometer as an absorber. Spectral measurements on a Fourier transform spectrometer show that the bolometer has useful sensitivity from visible wavelengths to beyond {approximately}200 {mu}m. This performance is clearly superior to that of a commercial room temperature pyroelectric detector. Some improvement appears possible.
