“…When frequency increases, NEP decreases (noise tempera− ture increases) greatly. Receivers based on room−tempera− ture Schottky diode mixers typically have radiometric sensi− tivities DT~0.05 K at n = 500 GHz and DT~0.5 K at 2.5 THz for a 1−s integration time and a 1−GHz predetection bandwidth [8] and SBD mixers noise temperature increases at n > 1 THz [76].…”

In the paper, issues associated with the development and exploitation of terahertz (THz) radiation detectors are discussed. The paper is written for those readers who desire an analysis of the latest developments in different type of THz radiation sensors (detectors), which play an increasing role in different areas of human activity (e.g., security, biological, drugs and explosions detection, imaging, astronomy applications, etc.). The basic physical phenomena and the recent progress in both direct and heterodyne detectors are discussed. More details concern Schottky barrier diodes, pair braking detectors, hot electron mixers, and field-effect transistor detectors. Also the operational conditions of THz detectors and their upper performance limits are discussed.

“…In addition, the output power of tunable submillimeter LO sources is generally quite low [33], so mixers with low LO power requirements are needed. Cryogenically cooled semiconductor diodes have been used for first-stage mixers in the past [43]- [46], although by now they have been replaced by superconducting tunnel junction (SIS) or HEB mixers.…”

“…As discussed in the previous section while photonic technologies can help in term of link efficiency, generating high data rate and coherence, the system still needs more output power at the transmitter in particular for applications such as backhaul where the distance will have to reach a kilometre. For example, a state of the art photonic emitter will offer about 1-mW output power at 300 GHz 26 and easily 40-Gbit/s data rate in a 50-GHz DSB bandwidth, while a state of the art room temperature operating receiver (Schottky-diode mixer based 68 ) would offer a detection sensitivity of 4 • 10 %&' W/Hz.…”
