An overview of solid-state electronic sources and detectors for Terahertz imaging

An overview of the solid-state electronic approaches for THz sources and detectors aiming at THz imaging is presented in this review paper. Various diode- and transistor-based THz sources are compared for their operation principles and the performances comparison is made based on the literature available at this moment. Similarly, diode- and transistor-based detectors are compared for their operation and performance. This paper is expected to provide a snap shot of current status of the solid-state THz electronics, serving to help those who want to get an initial idea of this field.
