Abstract
Recently, we have developed step-edge YBCO Josephson junctions with characteristic frequencies fc=(2e/h)(IcRn) of up to 5 THz (where I c and Rn are the junction´s critical current and normal-state resistance). Our project´s overall aim is to explore the capabilities of these junctions for several types of frequency translation, utilizing the junction´s ability to support very high frequency currents. These include high bandwidth mixing at CO2 laser (30 THz) and visible frequencies, low noise mixing at THz frequencies, and harmonic mixing from mm-wave up to THz frequencies
