摘要

We observed constant voltage steps for an overdamped Josephson array driven by current pulse trains generated by triggering a photo detector located in a cryostat with a mode locked fiber laser. We measured the voltages of the Josephson array as a function of an optical power. Quantized voltage steps were verified at multiples of about 10 mu V which corresponds to the repetition frequency of 50 MHz and the number of junctions of 100. A quantitative analysis was done on the current pulse shape which generated by the MSM detector. (C) 2007 Elsevier B.V. All rights reserved.
