Abstract
We have used a DC SQUID (superconducting quantum interference device) gradiometer to study vortex-antivortex pair creation in both two-dimensional superconducting films and Josephson junction arrays in the presence of 850 nm light irradiation. Specifically the experiments aim to distinguish between the formation of vortex-antivortex pairs by single-photon absorption and by thermal activation. A major objective for this experiment is to investigate the possibility of using vortex-antivortex pair creation and subsequent detection as the basis for a photon detector.
