TL;DR: In this article, temperature and external electrical field effects on propagation properties of a photonic liquid-crystal fibre composed of a solid-core photonic crystal fibre filled either with a prototype nematic liquid crystal characterized by extremely low (of the order of ~0.05) material birefringence or with a typical nematic pentylo-cyano-biphenyl, PCB (birefurringence of the order 2.2).

High Birefringence Isothiocyanato Tolane Liquid Crystals
TL;DR: In this paper, the phase transition temperatures, birefringence and visco-elastic coefficient of several high birerringence isothiocyanato-to-lane compounds were evaluated.
Journal ArticleDOI
Solution of the dark state problem in antiferroelectric liquid crystal displays
TL;DR: In this paper, it was shown that if the directors in alternating layers are orthogonal to each other, the AFLC acquires new optical properties such that the problem is eliminated, and a dark state extinction is achieved which is only limited by the quality of the polarizers.

Fast Switching Liquid Crystals for Color-Sequential LCDs
Abstract: High birefringence (0.3 < Deltan < 0.4) and relatively low-viscosity liquid crystal mixtures containing isothiocyanato tolane and isothiocyanato terphenyl liquid crystals are developed. A twisted-nematic (TN) 1.6-mum thin cell for color-sequential liquid crystal display with ~1-ms response time is demonstrated.
