Abstract
Abstract Phase locking of two grain-boundary Josephson junction oscillation is directly observed in the frequency range 40 GHz–2.5 THz at 77 K. The junctions are prepared from laser-ablated YBCO films on a bicrystal YSZ substrate. They are connected by a microstrip line for a.c. with an impedance of about 0.3 Ohm. The low impedance is achieved by evaporation of 0.5 μm BaF 2 followed by 0.3 μm of silver-ground plane. Further cooling up to 70 K results in about 10% upper frequency limit increase.
