AB  - Josephson junctions with high characteristic voltages IcRn and resistances Rn ranging from subohm values to several hundred ohms are required for various terahertz (THz) applications. Due to optimization of technology, [100]-tilt YBa2Cu3O7-x bicrystal Josephson junctions with an average IcRn (5 K) value of 7 mV at an Rn-range from 0.4 to 400 Ω have been fabricated on (320) bicrystal NdGaO3 substrates. Classical and frequencyselective detection of THz radiation have been demonstrated with the fabricated Josephson junctions. The main characteristics of Josephson oscillators, spectrum analyzers, admittance spectrometers, and classical detectors have been evaluated within this range of junction parameters, and promising results have been obtained.
