In this study, the proposed phase gratings are fabricated by the uniform lying helix (ULH) textures of cholesteric liquid crystals (CLCs). With the characteristics of LCs, an electrically tunable phase grating is realizable under ULH textures. Besides, the effect of the LC dimer, CB7CB, to ULH textures is investigated.
