Abstract

The response of a polycrystalline thin‐film Bi2Sr2CaCu2O8 superconducting stripe to short‐pulse far‐infrared (λ=447 μm) radiation is reported. Under constant current bias, a photosignal is generated when the maximum zero voltage current is exceeded. Measurements of the sensitivity as a function of temperature, bias current, and intensity reveal the signal source to be nonbolometric. The response ...
