Abstract
A layer stack includes a polymer layer including a plurality of regions with different refractive indices. The plurality of regions includes a first region including a first polymer composition having a first refractive index; a second region including a second polymer composition having a second refractive index different from the first refractive index; and a third region including a third polymer composition having a third refractive index different from the first and second refractive indices. The first polymer composition is different from the second polymer composition, and the first and second polymer compositions are different from the third polymer composition. The first refractive index is between 1.3 and 1.8, the second refractive index is between 1.3 and 1.8, and the third refractive index is between 1.3 and 1.8.
