摘要：A blue-phase liquid-crystal grating is proposed by applying a vertical electric field with lateral periodic distribution. Simulation on electric-field distribution was also carried out, the results of which suggest the alternation of isotropic and ordinary refractive indices in the lateral direction. Through the electrode configuration design, both 1 D and 2D gratings were demonstrated with high transmittance of ca. 85%. The diffraction efficiency of the first order reached up to 38.7% and 1 7.8% for the 1D and 2D cases, respectively. The field-induced fast phase modulation permits a rapid switching of diffraction orders down to the submillisecond scale.
