Experimental results are presented on the effects of optical radiation impinging on superconducting weak links and films. In-house fabricated weak links of various materials showed a lowering of critical current values dependent on radiation intensity. Also, specially modified commercial SQUIDS showed a lowering of both dc bias and rf bias required for SQUID operation as the optical intensity was increased. The possibilities of using high T/sub c/ materials for SQUID fabrication and the tuning of these devices via optical irradiation are discussed. (auth)
