    Abstract

    We demonstrate a process by which phase control of high-Tc superconductors can be achieved by photoswitching. In oxygen-deficient YBa 2Cu3O6+d, optical switching between two structural states can be achieved by applying visible and near-infrared light. The states also exhibit different transport properties, and thus this photoswitching gives an opportunity to control metastability and superconducting property in the same crystal as a function of photon density. With the help of scanning near-field optical microscope, we apply such a phase control technique to fabrication procedure for superconducting nano-components such as superconducting wires in insulating film and optical switches.
