Parasitic mixing in photomixers as continuous wave terahertz sources

Scientific Reports
We present observations of parasitic frequency components in the emission spectrum of typical photomixer sources for continuous wave (CW) terahertz generation. Broadband tunable photomixer systems are often used in combination with direct power detectors,

Die Reaktionsrate eines InGaAs Terahertz Detektors in Fliegeform bei Zimmertemperatur mit gebrochener Symmetrie

, 2022
S.549-550A bow-tie InGaAs with broken symmetry has been designed for terahertz detection at room temperature. An active part of the detector consists of a two-dimensional electron gas which is heated non-uniformly with incident radiation.

A Versatile Illumination System for Real-Time Terahertz Imaging

Sensors, 2020
Terahertz technologies are attracting strong interest from high-end industrial fields, and particularly for non-destructive-testing purposes. Currently lacking compactness, integrability as well as adaptability for those implementations, the development ...
