Abstract
Experimental photoresponse study of granular YBa2Cu3O7-x (YBCO) weak l ink is reported, The Josephson critical current I-c is suppressed with light illumination of the junction, produced mainly from optical gene ration of quasiparticles. At lower temperature (T = 64.5 K), the hyste resis in I-V characteristic of the weak link appears, which may be fou nd useful for optical detection purpose. This was supported from preli minary experiments.
