Abstract

Based on the polarization-sensitive terahertz time-domain spectroscopy, we measured the birefringence for Al 2 O 3 and LiNbO 3 single crystals, which correspond to trigonal structures that have an uniaxial birefringence, in the THz frequency range of 0.25 to 1.4 THz . For more comprehensive understanding of the THz birefringence, the measured birefringence is compared with the results of ab initio calculations. The measured birefringence shows good agreement with the calculated value.
