Dual-frequency liquid crystal gels with submillisecond response time
نویسندگان
چکیده
Two types of gels using dual-frequency liquid crystal are demonstrated. The one using a homogeneous cell shows anisotropic scattering behavior while the other prepared using a cell without polyimide alignment layers exhibits isotropic scattering properties. Both liquid crystal gels are highly transparent in the voltage-off state. Light scattering occurs when a high frequency voltage is applied. The isotropic gel exhibits a high contrast ratio and submillisecond response time. Potential applications of these gels for switchable polarizer, telecom optical switch, and reflective displays are emphasized. © 2004 American Institute of Physics. [DOI: 10.1063/1.1799249]

Dual-Frequency Addressed Infrared Liquid Crystal Phase Modulators with Submillisecond Response Time
Dynamic response of a dual-frequency liquid crystal (DFLC) based near infrared phase modulator is investigated through numerical simulations and experiments. The relationships between the optical response times and various voltage driving conditions are studied. An optical phase retarder operating at 1.55 lm wavelength is demonstrated by using our homemade high figure-of-merit DFLC mixture. To ...
متن کاملFast response dual-frequency liquid crystal switch with photo-patterned alignments.
A dual-frequency liquid crystal based optical switch with orthogonally photo-patterned alignments is designed and fabricated. The cell gap is theoretically optimized for high switching performance. The measured extinction ratio of first diffraction order is over 20 dB with a low electric field of 3 V/μm. The switch On-Off time are measured to be 350 μs and 600 μs, respectively, both of which h...
متن کاملA low voltage and submillisecond-response polymer-stabilized blue phase liquid crystal
We report a polymer-stabilized blue phase liquid crystal (BPLC) whose Kerr constant is about 2.2 larger than previous record. When filled in a 3.2-lm-thick vertical field switching cell, the on-state voltage is merely 8.4 V (at k1⁄4 514 nm) while keeping submillisecond response time and negligible hysteresis (<1%) at the room temperature. These results imply that the dawn of BPLC era for high s...
متن کاملHysteresis-free and submillisecond-response polymer network liquid crystal.
We demonstrate a polymer network liquid crystal (PNLC) with negligible hysteresis while keeping submillisecond response time. By doping about 1% dodecyl acrylate (C12A) into the liquid crystal/monomer precursor, both hysteresis and residual birefringence are almost completely eliminated. The operating voltage and scattering properties remain nearly intact, but the tradeoff is enhanced double re...
متن کاملSubmillisecond-response liquid crystal for high-resolution virtual reality displays.
We report a vertically-aligned liquid crystal display (LCD) device with submillisecond response time, high transmittance, and low operation voltage. The top substrate has a common electrode, while the bottom substrate consists of hole-patterned fringing-field-switching (FFS) pixel electrodes. A negative dielectric anisotropy LC is employed. In the voltage-on state, the LC directors are reorient...
