A optically controlled cholesteric grating is proposed. The dye-doped cholesteric grating (DDCLC grating) can be rotated by changing the polarization of the pump-beam. The experiment results reveal that the orientation of the cholesteric grating can be rotated in a specific range decided by the alignment direction of the two substrates.
Moreover, the hybrid alignment condition for the cholesteric grating is also investigated. When the ratio of d/p is larger than 0.5,the cholesteric grating is observable without applying voltage in hybrid aligned cholesteric cell, and the cholesteric gratings with hybrid alignment can have a 360 rotation angle, thus achieve the two dimension beam steering cholesteric.
