Abstract
The photoresponse of granular Bi2Sr2CaCu2O8 and of epitaxial YBa2Cu3O7-δ thin films has been investigated at wavelengths between 10 μm and 944 μm. In addition to a bolometric signal we observe for the granular Bi-based films a nonbolometric response at temperatures T <80 K. The dependence of the signal on intensity, applied magnetic field and wavelength is consistent with an ac josephson effect occurring at the grain boundaries.
