US Patent-Terahertz electromagnetic wave generator, terahertz spectrometer and method of generating terahertz electromagnetic wave
United States Patent 9389124
Inventors:Takahashi, Kohei (Osaka, JP) Kanno, Tsutomu (Kyoto, JP) Sakai, Akihiro (Nara, JP) Yamada, Yuka (Nara, JP)
A terahertz electromagnetic wave generator according to the present disclosure includes: a substrate; a thermoelectric material layer which is supported by the substrate and which has a surface; and a pulsed laser light source system which locally heats the thermoelectric material layer with an edge of the surface of the thermoelectric material layer irradiated with pulsed light, thereby generating a terahertz electromagnetic wave from the thermoelectric material layer.
