Outline of Final Research Achievements

We fabricated terahertz emitters combining microstructures resonating with terahertz waves and nanostructures resonating with light, and investigated their properties. A film with spontaneously formed nanostructures was made by coating a fused silica substrate with a silver nano-particle ink and baking it. By removing part of this film with laser machining, split ring resonators with a size of several tens micrometers were fabricated. Peak frequencies in the terahertz spectra emitted by femtosecond laser pulse irradiation depend on the size and direction of the ring, and are confirmed to be near the resonant frequency of the ring measured by terahertz time-domain spectroscopy.
