首次报道了Bi 2Sr 2CaCu<sub>2</sub> O<sub>8+δ</sub>固体薄膜本征约瑟夫森结器件的太赫兹辐射。<sub></sub><sub></sub>结果表明，<italic>在原位</italic>激光修剪的电流引线结构可以激活最初的太赫兹无源器件。微调增加了感抗，改善了本征约瑟夫森结的RF隔离。据认为，射频隔离是一个关键组成部分，以保持谐振腔内的固有约瑟夫森结必不可少的，以创建太赫兹波从固体Bi-2212膜IJJ设备。
This is the first report of terahertz (THz) radiation from intrinsic Josephson junction devices made of solid Bi<sub> 2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+δ</sub> thin films. It is shown that <italic>in situ</italic> laser trimming of the current lead structure could activate initially THz inactive devices. The trimming increased inductive reactance and improved RF isolation of intrinsic Josephson junctions. It is considered that the RF isolation is a key component to maintain a cavity resonance within intrinsic Josephson junctions essential to create THz waves from solid Bi-2212 film IJJ devices.
