Terahertz wire-grid circular polarizer tuned by lock-in detection method
For our magneto-optical measurements we designed and successfully tested a broadband-tunable terahertz circular polarizer employable with our far-infrared/THz laser source working in the range of 0.25–7.5 THz. This unique experimental setup allows us to measure cyclotron resonance of electrons (in semiconductors) and vortices (in superconductors).
