Abstract

Various bistable switching modes in nematic liquid crystals with frequency inversion of the sign of dielectric anisotropy are revealed and investigated. Switching between states with different helicoidal distributions of the director field of a liquid crystal, as well as between uniform and helicoidal states, is realized by dual-frequency waveforms of a driving voltage. A distinctive feature of the dual-frequency switching is that the uniform planar distribution of the director field may correspond to a thermodynamically equilibrium state, and the chirality of an LC is not a necessary condition for switching to a helicoidal state.

Localised polymer networks in chiral nematic liquid crystals for high speed photonic switching

Journal Article Salter, Patrick; Booth, Martin; Morris, Stephen - Journal of Applied Physics

Self-assembled periodic structures based upon chiral liquid crystalline materials have significant potential in the field of photonics ranging from fast-switching optoelectronic devices to low-threshold lasers. The flexoelectro-optic effect, which is observed in chiral nematic liquid crystals (LCs) when an electric field is applied perpendicular to the helical axis, has significant potential as it exhibits analogue switching in 10–100 μs. However, the major technological barrier that prohibits the commercial realisation of this electro-optic effect is the requirement of a uniform, in-plane alignment of the helix axis between glass substrates. Here, it is shown that periodic polymer structures engineered in the nematic phasemore »« less

Nano-electromechanical rotation of graphene and giant enhancement in dielectric anisotropy in a liquid crystal

Journal Article Basu, Rajratan; Kinnamon, Daniel; Garvey, Alfred - Applied Physics Letters

A nematic liquid crystal (LC) is doped with dilute concentrations of pristine monolayer graphene (GP) flakes, and the LC + GP hybrids are found to exhibit a dramatic increase in the dielectric anisotropy. Electric field-dependent conductance studies reveal that the graphene flakes follow the nematic director that mechanically rotates on increasing an applied electric field. Further studies show that the π–π electron stacking, between the graphene's honeycomb structure and the LC's benzene rings, stabilizes pseudo-nematic domains that collectively amplify the dielectric anisotropy by improving the orientational order parameter in the nematic phase. These anisotropic domains interact with the external electricmore »« less

Switching and intrinsic position bistability of soliton beams in chiral nematic liquid crystals

Journal Article Beeckman, Jeroen; Madani, Abbas; Vanbrabant, Pieter; ... - Physical Review. A

We study theoretically and experimentally the propagation of light beams in chiral nematic liquid crystals. Despite the rather complex refractive index distribution of these crystals, their reorientational nonlinearity can compensate for diffraction, leading to robust solitonlike beams propagating along helical trajectories. We demonstrate that, due to a symmetry-breaking instability of the liquid crystal structure, these beams undergo abrupt switching and bistability, features that are of potential interest for applications to all-optical signal processing.

New bistable cholesteric liquid-crystal display

Journal Article Berreman, D; Heffner, W - Appl. Phys. Lett.; (United States)

We have made a new type of cholesteric liquid-crystal display device that is bistable in the absence of an applied field. One of the two stable states has 360/sup 0/ of twist between the two surfaces. The other is an untwisted state, like an unstrained nematic with all directors parallel. One method of switching is to apply a pulse of about 3 V or more between the cell surfaces, to obtain the twisted state or a pulse of about 1.5--2 V to obtain the untwisted state. Lesser pulses have no lasting effect. These switching characteristics have promise for displays withmore » large numbers of characters.« less

A fast anharmonic mode in electrooptical switching of liquid crystal structures based on chiral nematics

Journal Article Barnik, M; Blinov, L; Shtykov, N - Journal of Experimental and Theoretical Physics

Polarization, spectral, and relaxation features of a new electrooptical effect in oriented layers of chiral nematic liquid crystals (LCs) are considered. The physics behind this electrooptical effect is the induction of higher order spatial harmonics in the helical distribution of the director field, which ensures the high speed of electrooptical response. It is shown that the spectral properties of the electrooptical response can be effectively controlled by varying the optical anisotropy of the LC and the pitch of the helical structure.
