This work presents a multi-domain Bragg mirror based on a polymer-dispersed liquid crystal (PDLC) film using holographic recording. The mirror has a three-dimensionally (3-D) ordered structure that consists of a one-dimensional (1-D) Bragg grating and a two-dimensional (2-D) Raman–Nath grating. The green imaginary reflected by the Bragg grating could be switched at a fast switching speed. Additionally, the intensity of the reflected light can be varied with the applied voltage at various frequencies.
