Abstract:
A zoned waveplate has a series of transversely stacked birefringent zones alternating with non-birefringent zones. The birefringent and non-birefringent zones are integrally formed upon an AR-coated face of a single substrate by patterning the AR coated face of the substrate with zero-order sub-wavelength form-birefringent gratings configured to have a target retardance. The layer structure of the AR coating is designed to provide the target birefringence in the patterned zones and the reflection suppression.

Claim (Index 41):
The method of  claim 40 , wherein a plurality of gaps extend through the spacer layer and the index matching layer, thereby forming a surface-relief grating.
