Self-normalizing phase measurement in multimode terahertz spectroscopy based on photomixing of three lasers
K. Thirunavukkuarasu, M. Langenbach, A. Roggenbuck +4
Photomixing of two near-infrared lasers is well established for continuous-wave terahertz spectroscopy. Photomixing of three lasers allows us to measure at three terahertz frequenc…

Enhancing the stability of a continuous-wave terahertz system by photocurrent normalization
A. Roggenbuck, M. Langenbach, K. Thirunavukkuarasu +6
In a continuous-wave terahertz system based on photomixing, the measured amplitude of the terahertz signal shows an uncertainty due to drifts of the responsivities of the photomixe…
