N2 - Y-Ba-Cu-O thin film infrared detectors were fabricated and studied with a CO2 laser. Operation of the detector in both the bolometric and nonbolometric modes was investigated. In the bolometric mode, the detectivity of the detector at 90 K was 2.1 × 108 cm Hz 1 2 W-1 with a response time of 15 μs, corresponding to a bandwidth of 70 KHz. The speed of the detector in the nonbolometric mode was much faster and was beyond the instrument resolution of 10 ns (100 MHz). However, the detectivity could not be determined due to the extremely low noise. The superconducting film quality is critical to the performance of these detectors.
