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…
Terahertz whispering gallery mode bubble resonator
Dominik Walter Vogt, Rainer Leonhardt
Whispering gallery mode (WGM) resonators are compelling optical devices, however they are nearly unexplored in the terahertz (THz) domain. In this letter, we report on THz WGMs in…
