Paper Abstract

For non-normal incidence angles, it has been shown that the polarization state may be controlled by reflection through the use of specially designed multilayer coatings. An optimization I has been used to determine layer thickness for a coating design tha. produces a 90° phase shift between the p and s polarization comppnents over a wavelength range of Δλ/λ0 = ± 5%. A particular 20 layer design produces 90° ± 1° phase shift over this spectral range while maintaining an average reflectivity of over 99.9%. A tolerance analysis on this design indicates that the coating layers must be deposited within ± 1% in order to achieve ± 3° phase shift over the spectral range.
