Abstract:

A Noise Source(NS) is a device that generates controllable noise(with controllable frequency and power)，and it is an important tool in the development process of devices. Terahertz noise sources have important applications in terahertz device noise figure testing, calibration of space-borne microwave radiometers, imaging, and spectral analysis. This article systematically reviews the development and research status of Terahertz(THz) noise sources at home and abroad, analyzes the technical characteristics of terahertz noise sources based on thermodynamics, electronics, and photonics, and looks forward to their future development directions.
