2111679 9300720 PCTABS00019 Active superconductive devices are formed having a variable conductive element in electromagnetic contact with a superconductor. In one embodiment, a variable ohmic conductive device (16) such as a photoconductor, is placed adjacent a superconductor (12). By varying the optical radiation on the photoconductor, the electromagnetic environment adjacent the superconductor is changed, resulting in changed electrical properties. The superconductor may be patterned as a reject filter (10, 12, 14) with a photoconductor forming a microwave switch. Alternatively, a delay line (40) plus variable ohmic element (46) forms a phase shifter.
