Summary:Polarization properties of transmission THz wave through the extremely thick LC device were measured by using optically pumped submillimeter laser. From our previous work, LC molecular orientation anisotropy was confirmed in a LC immersed membrane film. In this study, we fabricate the extremely thick homogenous LC cell by stacking LC immersed membrane films. Polarization sate of THz wave was changed by the LC device and circular polarized THz wave was obtained at 2.5 THz. Anisotropy of absorption coefficient was evaluated by changing the incident terahertz polarization direction.
