| Outline of Final Research Achievements |
Frequency up-conversion from millimeter waves of frequencies between 90-100 GHz to 0.3 THz-band terahertz waves through the Doppler effect have been observed experimentally using a slot transmission line on an optically excited GaAs substrate. The maximum frequency up-conversion ratio was 4.2. The measured amplitudes of the terahertz waves, however, have been lower than one tenth compared to theoretical predictions. The cause of that is still under investigation. In this research project, new conversion method from periodic static fields to terahertz waves using a metal waveguide as a transmission line has been proposed and experimentally demonstrated. Using the conversion method, periodic terahertz waves at frequencies between 0.2-0.6 THz have been successfully generated.
