Generation and Detection of Broadband Pulsed Terahertz Radiation

Abstract

The generation and detection of ultrashort electromagnetic radiation is reviewed. The detection of ultrashort electromagnetic pulses with the electro-optic sampling techniques is introduced by insisting on its broad detectable bandwidth. The principles and experimental techniques for the optical rectification effect are described for the broadband generation of pulsed terahertz radiation. In addition to these techniques using nonlinear optical effects, the recent findings on the photoconductive antennas enabling detection and generation of ultra-broadband pulsed terahertz radiation are described.
