We discuss the design and fabrication of coatings that are antireflecting for -polarized light at normal incidence and are purposely reflecting for -polarized light. A single birefringent material, such as obliquely deposited zirconium oxide, forms the layers of the coating. Typical experimental results for a six-layer zirconium oxide anisotropic antireflection coating are and . Potential applications of the coatings include polarization-selection devices for lasers.
