摘　　要：研究了激光辐照下约瑟夫森结的直流 I- V特性变化 ,并对 - 曲线下移的实验结果进行了分析 ,认为是光拆库柏对效应所致 .该结果为发展一种新的可见光探测器提供了思路.In this paper,variation of DC I-V curves of Josephson junction was observed,and the reduction of I-V curve was interpreted qualitatively.Photon breaking Copper pair effect was reckoned as the main reason.An idea of creating a new kind of optical detector was provided from this experiment.
