Abstract

The ability of a weakly anisotropic thin film to modulate the polarization state of light was considered. We found that, in a configuration for enhanced polarization conversion, most polarization states can be generated by tuning the direction of incident linear polarization and the aspect of the anisotropic thin film. The modulation for omniform polarization state can be extended to a broad wavelength range by adding an isotropic thin film in the system.
