摘要：Blue phase liquid crystal Dammann grating is demonstrated as an optical array generator. The phase profile is formed by the alternation of isotropic refractive index and vertical field induced ordinary index. Periodical Dammann grating can generate equal energy distributed optical array. When forked dislocations are introduced, multiple optical vortex beams with different topological charges are generated. This approach supplies a novel design for fast-response optical array generator, which has great potentials in array illumination, beam shaping and optical communications.
