YBa(2)Cu3O(7-delta) thin films may be epitaxially grows, on suitably prepared substrates, with a non-zero tilt angle between the film's c-axis and its surface normal. These films are fast, room-temperature, thermoelectric detectors with a response extending from UV to FIR wavelengths. We have found that tilted c-axis films, when cooled below T-c, also exhibit a fast and sensitive Josphson photoresponse to 250 mu m and 496 mu m radiation, in contrast to the nil response of c-axis normal films. It is believed that the non-zero component of the radiation electric field along the c-axis of tilted films modulates relatively weak Josephson critical currents in this direction, generating a photoresponse from current biased samples.
