This work demonstrates axially symmetric polarization converters based on photo‐alignment in dye‐doped liquid crystal (DDLC) films. A linear‐shape and linearly polarized beam is applied onto a rotated homogeneous DDLC cell to achieve three axially symmetric polarizations — radial, azimuthal and vortical. Additionally, the spiral degree of the axially symmetric vortical polarization can be controlled by varying the polarization of the pumping light and the simulation results agree well with the experiment.
