Fast Response and Low Voltage Dual Frequency Liquid Crystals.

摘要

Two types of liquid crystal phase modulators: dual frequency liquid crystal (DFLC) and polymer network liquid crystal (PNLC) with 2-pi phase change and submillisecond response time were demonstrated. For DFLC, a record-high birefringence DFLC, an ultra-low crossover frequency DFLC (UCF-01), and a high figure-of-merit DFLC (UCF-02) intended for elevated temperature operation were developed. The figure-of-merit of UCF-02 is 5X higher than that of Merck MLC- 2048. For PNLC, a PNLC phase modulator with low scattering.
