We report two high birefringence and low viscosity nematic mixtures for phase-only liquid-crystal-on-silicon spatial light modulators. The measured response time (on + off) of a test cell with 2? phase change at 1550 nm, 5 V operation voltage, 40 °C is faster than 10 ms. To improve the photostability, distributed Bragg reflector designed to cutoff harmful ultraviolet blue wavelengths. These mat...
