液晶（Liquid Crystal，LC）器件具有高可调谐性和低功耗，不仅在可见光区而且在太赫兹区都很重要。在这项研究中，双折射和吸收损失的氢键液晶估计在2.5太赫兹。结果表明，在氢键液晶中引入烷氧基链可以有效地提高太赫兹区的双折射。这些结果表明，氢键液晶是一个强有力的候选人，为未来的太赫兹器件，因为它们在太赫兹区域的优异性能。
SUMMARY 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 e ff ective to increase birefringence in terahertz region. These results indicate that hydrogen-bonded LCs are a strong candidate for future terahertz devices because of their excellent properties in the terahertz region.
