Abstract
We report the generation and detection of ultrabroadband THz radiation using photoconductive antennas as the emitter and the detector. The photoconductive antenna showed a detection bandwidth as broad as the electro-optic sampling detectors. On the other hand, the photoconductive emitter showed a spectral bandwidth much narrower than that of the electro-optic emitters. We discuss the bandwidth properties of the photoconductive emitters and detectors in comparison with their electro-optic counterparts.
