Polarization diffraction optical elements formed by the photoalignment of a polarization-sensitive polymer liquid crystal are presented. Specifically, we introduce an incident angle dependence-reduced polarization grating with biaxial anisotropy and a wavefront aberration-corrected geometric-phase lens.
