Research Abstract

The properties of terahertz emitter made of high-temperature superconductor (HTSC) have been revealed in this project. We have also been successful in designing the properties of the device for the first time. Terahertz waves laying between radio waves and light waves show peculiar features of rather high transmittance and high spacial resolution and its technology has been investigated intensively. This study reveals that the terahertz wave from an HTSC emitter is highly coherent, so that the HTSC emitter can be utilized for a source of carrier wave for next-generation high-speed communication infrastructures. It is also found that the emission frequency of a device is externally tunable. The poor reproduciblity of devices mentioned in previous studies has been improved.
