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…

Group delay in THz spectroscopy with ultra-wideband log-spiral antennae
M. Langenbach, A. Roggenbuck, I. Cámara Mayorga +4
We report on the group delay observed in continuous-wave terahertz spectroscopy based on photomixing with phase-sensitive homodyne detection. We discuss the different contributions…

Phase-predictable tuning of single-frequency optical synthesizers
Felix Rohde, Erik Benkler, Thomas Puppe +3
We investigate the tuning behavior of a novel type of single-frequency optical synthesizers by phase comparison of the output signals of two identical devices. We achieve phase-sta…
