摘要
We report on several photoconductive (PC) geometries for the generation of both guided-wave and free-space terahertz (THz) waveforms. It is found that guided-wave THz electrical waveforms can be produced through both PC self-switching and frozen wave generation-eliminating the need for an ultrashort carrier lifetime in the semiconductor substrate. The concept of PC switching is also applied to, the generation of free-space THz waveforms, and various ZnSe detectors are investigated as potential electro-optic THz sensors.
