Outline of Final Research Achievements

In this research, we tried to increase its output by combining a high-temperature superconductor terahertz oscillator with an external resonator. The terahertz electromagnetic wave is expected to be applied in a wide variety of fields such as high speed communication, medical care, and security. The development of solid state oscillator in terahertz regime is urgent problem to be solved. We aimed at high power output from superconductor terahertz oscillators, by introducing a gold ground plane to serially-connected two superconducting oscillators for the first time. Since the applied voltage range during oscillation before and after the formation of the ground plane changed sharply, it was suggested that the resonance mode via the ground plane was realized. In addition, from the viewpoint of eliminating impedance mismatching, by the dilute hydrochloric acid reforming method, we worked on improving the processing procedures for realizing the higher output power.
