A polarization grating (PG) written in an azo-dye-doped film of polymer-ball-type polymer dispersed liquid crystals (PBT-PDLCs) was investigated. The writing beams were two mutually orthogonal (s- and p-polarized) polarized beams, The PG resulted from the LC molecular reorientation due to their interaction with the dye molecules adsorbed on the surface of the polymer balls. Polarization properties of the diffracted beams and the grating pattern were studied under a polarizing optical microscope with a crossed analyzer. The results indicate that the PG diffracts the linearly polarized incident light into beams with different polarizations. Accordingly, the grating can be employed as an un-polarized or polarized beam splitter depending on the polarization of the incident light. The simulation based on the Jones matrix method is developed and the results correspond well with the experimental results.
