Polarization-variable emitter for terahertz time-domain spectroscopy

Bulgarevich, Dmitry S.; Watanabe, Makoto; Shiwa, Mitsuharu; Niehues, Gudrun; Kitahara, Hideaki; Tani, Masahiko

Abstract:
We report on the progress in the development of linear polarization-variable multielectrode emitters for terahertz time-domain spectroscopy. The results on its microfabrication, the finite element method modeling of appropriate bias distribution between electrodes, the finite-difference time-domain simulated spectral output, and actual experimental testing are presented. The rotation of the emitted terahertz field with linear polarization on an angle multiple of 45° can be achieved by synchronized bias and single polarizer rotations.
