Paper Abstract
Over the last decades, scientists have paid growing attention towards the terahertz properties of liquid crystals. On the
one hand, the dielectric properties of liquid crystals are relatively unexplored at terahertz frequencies, and the observed
low-energy phenomena are not yet well understood. On the other hand, terahertz technology requires switchable devices,
in which liquid crystals could potentially serve as a base material. This paper gives an overview of the research done so
far on the properties and applications of liquid crystals in the terahertz frequency range. The path from first liquid-crystal
terahertz experiments to comprehensive studies of their structure-property relation is outlined. Furthermore, the
evolution from basic concepts to first liquid-crystal terahertz devices is sketched, and prospects as well as future
challenges are discussed. Due to the development of compact and cost-efficient components, terahertz spectrometers
matured from room-filling laboratory instruments to compact, reliable scientific tools. Modern terahertz systems are thus
also covered in this report. Liquid-crystal devices could help terahertz technology continue this trend, and pave the way
to a wider range of application.
