Estimating the Birefringence and Absorption Losses of Hydrogen-bonded Liquid Crystals with Alkoxy Chains at 2.5 THz

Liquid crystal (LC) device has high tunability with low power consumption and it is important not only in visible region but also in terahertz region. In this study, birefringence and absorption losses of hydrogen-bonded LC was estimated at 2.5 THz. Our results indicate that introduction of alkoxy chain to hydrogen-bonded LC is effective to increase birefringence in terahertz region. These results indicate that hydrogenbonded LCs are a strong candidate for future terahertz devices because of their excellent properties in the terahertz region.
