We demonstrate a scattering-free polymer network liquid crystal spatial light modulator with submillisecond response time and 2-pi phase change in the short-wavelength infrared region. As shown in Fig.1, when the operation temperature increases from 25oC to 70oC, the response time decreases from 220 �s to 30 �s, but the operating voltage at ?=1.06 �m increases from 70V to 90V. Meanwhile, hysteresis is suppressed from 7.7% to 2%. If reflective mode is employed, operating voltage can be further reduced.
