Superconductive electronics is well known to offer substantial performance advantages over conventional technologies with respect to high-speed, low-power dissipation and high- frequency operation. Before the discovery of high-temperature superconductivity, these benefits could only be obtained at liquid helium temperature. Devices and circuits based on HTS materials offer the promise of operation at temperatures as high as 77 K. The key element of most superconductive circuits is the Josephson junction, and developing a useful and reliable junction made from high-temperature superconductors (HTS) remains a central issue for the superconductive electronics community. The current status of HTS Josephson devices as they are being developed by a number of laboratories is reviewed. Recent progress by several groups has greatly enhanced the prospects for developing a circuit process based on HTS Josephson devices.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.
