An optical detector prepared by high T(subscript c) superconducting thin film has been discussed. The device has been made from YBaCuO superconducting thin film with zero resistance at more than 80 K on a ZrO(subscript 2) substrate. A pattern of the device with the dimension of the microbridge is formed through photolithographic process. Electrical contacts are made by evaporating gold or silver with thickness of 0.5 - 1 micrometers . The sample is then placed in a dewar with an infrared window and is cooled by liquid nitrogen. A blackbody source at 800 K is used to measure the responsivity of the detector, and the infrared radiation is chopped at frequencies between 6.3 and 2000 Hz. The detector output with the detectivity larger than 10(superscript 9) cmHz(superscript 1/2)/w and a typical responsivity value as large as 10(superscript 3) V/w is observed on both lock-in amplifier and root-mean-square voltmeter. In addition, the mechanism of optical detection and the methods to improve the sensitivity have been described.
