| Outline of Final Research Achievements |
On terahertz radiations from high-Tc superconductors, we have been successful in emission of circularly-polarized waves from truncated-edged mesa structures. This feature is useful for applications of mobile communications. Furthermore, time-domain spectroscopy measurements were progressed in HTSC terahertz emitters to verify highly-coherent emission from them. In order to have higher emission power, we designed module structures which may suppress temperature rise of superconducting device. The module was tested by comparing emission properties of actual emitters.
