We report polarization analysis of higher order diffraction beam from polarization gratings in two types of photoreactive polymer liquid crystals (PPLCs). The polarization gratings are created from the photoreaction of PPLCs and finally induced molecular reorientation by annealing. In this work, investigations were carried out on two types of polarization gratings fabricated by different method and PPLCs. First polarization grating was fabricated by using hologram recording technique with non-polarized 365 nm and linearly polarized 633 nm light in PPLCs with azobenzene side groups. Secondly one was fabricated by new method using photomask for irradiation of linearly polarized UV lamp in photocrosslinkable polymer liquid crystals. Results of the polarization analysis of two polarization gratings in the higher diffraction orders were explained by general diffraction theory described by Jones matrices.
