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…
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…
ATLAS Pixel Opto-Electronics
K. E. Arms, P. Buchholz, K. K. Gan +13
We have developed two radiation-hard ASICs for optical data transmission in the ATLAS pixel detector at the LHC at CERN: a driver chip for a Vertical Cavity Surface Emitting Laser…
Radiation-Hard Opto-Link for the Atlas Pixel Detector
K. K. Gan
The on-detector optical link of the ATLAS pixel detector contains radiation-hard receiver chips to decode bi-phase marked signals received on PIN arrays and data transmitter chips…
