Abstract (in Japanese) (See Japanese page) 
(in English) We present apparently the first observation of sub-terahertz electromagnetic wave emission from GaN based large aperture photoconductive switches (LA-PCSWs) excited by ultraviolet femtosecond laser pulses. The photoconductive layer of the GaN LA-PCSW is doped with carbon giving rise to a resistivity as high as 60Mcm. The absolute energy of the emitted radiation pulses is measured to be 93.3pJ/pulse under 500V bias voltage. The Fourier spectrum of the measured pulse by the time-domain-spectroscopy shows the main components lie in 0.1-0.2 THz regime.
