ABSTRACT:
A superconducting network which, through the use of optical illumination, can form a selectable array of superconducting microstrip transmission lines or other electrical elements. The invention uses optical illumination to produce quasiparticles which cause selected physical parts of the network to be electrically nonconductive and thereby define the nonilluminated conductor's shape, physical size, and electrical characteristics. Network reconfigurability to produce several different devices and functions from a single high or low temperature superconductive chip is a disclosed utilization of the invention. The employed optical illumination produces phase change within the superconducting material to provide specific chip architectures. Reconfiguring of the device characteristics is achieved by changing the optical input intensity, spatial orientation, wavelength or combinations of these factors. A plurality of delay line configurations are disclosed as examples.
