Ultra-high precision comb-locked terahertz frequency-domain spectroscopy of whispering-gallery modes
Sebastian Müller, Kane Hill, Dominik Walter Vogt +2
We demonstrate the capabilities of a novel frequency-domain terahertz spectrometer based on a comb-locked frequency synthesizer, which provides absolute frequency calibration. The…
Gallium arsenide whispering gallery mode resonators for terahertz photonics
Mallika Irene Suresh, Harald G. L. Schwefel, Dominik Walter Vogt
As the field of terahertz (THz) photonics advances, we present a monolithic gallium arsenide (GaAs) disk-shaped whispering gallery mode resonator that has potential as a component…
Terahertz microresonators for material characterisation
Dominik Walter Vogt
Terahertz (THz) technology is rapidly evolving, and the advancement of data and information processing devices is essential. Silicon THz microresonators provide perfect platforms t…
Microresonator frequency reference for terahertz precision sensing and metrology
Rishabh Gandhi, Rainer Leonhardt, Dominik Walter Vogt
Highly sensitive terahertz (THz) sensors for a myriad of applications are rapidly evolving. A widespread sensor concept is based on the detection of minute resonance frequency shif…
Anomalous blue-shift of terahertz whispering-gallery modes via dielectric and metallic tuning
Dominik Walter Vogt, Angus Harvey Jones, Harald G. L. Schwefel +1
The vast majority of resonant systems show a red-shift for the resonance frequency when a perturbation, e.g. losses, are introduced to the system. In contrast, here we report for t…
Coherent continuous wave terahertz spectroscopy using Hilbert transformation
Dominik Walter Vogt, Miro Erkintalo, Rainer Leonhardt
Coherent continuous wave (CW) terahertz spectroscopy is an extremely valuable technique that allows for the interrogation of systems that exhibit narrow resonances in the terahertz…
