The spectral region between light and electrical wave is known as terahertz(THz) region from the viewpoint of its frequency. This far-infrared spectral region has recentry attracted considerable attention for its potential application in spectrscopy, imaging, telecommunications, medical analysis, and so on.
Terahertz photoconductive switch can generate/detect terahertz electromagnetic wave with femtosecond pulse laser as an excitation light source. When constructing terahertz time domain spectroscopy, two modules are required for emission and detection.
