Emission of Continuous THz Waves by Making Use of Superconductors and Its Applications

Research Project Outline

High temperature superconductors consist of thin CuO2 superconducting layers which stack in an atomic level, forming multi-Josephson junctions in a crystal. By exciting Josephson plasma in all Josephson junctions in a crystal synchronously we recently succeeded in generating intense, coherent and monochromatic continuous THz waves similar to LASER. We clarify the physical mechanism of this emission phenomenon and develop technology to generate more intense THz waves. We also employ spectroscopy of matter using this THz waves.
