Many optical devices that can be used in THz systems are continuously being researched and developed. Among them, liquid crystal (LC)-based polarizers and phase shifting devices have also been developed. The LC devices used in the THz system are fabricated in the form of a cell. The substrate of the cell should be transparent with low absorption in the THz frequency range. In the THz frequency band, research and development using various glass materials such as BK7 glass, slide glass, and quartz as substrates have been reported.
In this paper, we report the measurement results of the refractive indices and birefringence of glass materials in the THz band and the possibility of using them as substrates for LC cells. In addition, based on these results, we report the results of measuring refractive indices, absorption coefficient, and birefringence in the THz band after fabricating a LC cell.
