摘要

An electrically tunable mode is proposed to overcome the bottleneck prob-lem of a conventional polymer dispersed liquid crystal (PDLC) grating and realize its low threshold and high contrast through an alignment-controlled PDLC. The results indicate that the threshold voltage Vpp of the grating is as low as 0.75-0.8 V, the sat-uration voltage Vpp is 7 V and the contrast ratio of the grating reaches 245, which is about three times larger than the conventional PDLC grating. Stability testing indicates a stable state of contrast during a long time.
