Claim 9:
10. The method of claim 9, wherein the birefringent material in the second layer having another optical interface to a substrate with surface features, wherein a refractive index difference associated with the other optical interface depends on the polarization state of an incident light, and
wherein the light is scattered in a first direction when the polarization state of the light is altered into the first polarization state further corresponding to a first refractive index difference associated with the other optical interface, and
wherein the light is scattered in a second direction when the polarization state of the light is altered into a second polarization state further corresponding to a second refractive index difference associated with the other optical interface.
