Abstract-Polarization-variable emitter for terahertz time-domain spectroscopy

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

We report on the progress in the development of linear polarization-variable multi-electrode 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.
