Abstract:
Disclosed is an improved diffraction structure for 3D display systems. The improved diffraction structure includes an intermediate layer that resides between a waveguide substrate and a top grating surface. The top grating surface comprises a first material that corresponds to a first refractive index value, the underlayer comprises a second material that corresponds to a second refractive index value, and the substrate comprises a third material that corresponds to a third refractive index value.

Claim (Index 12):
The system of  claim 11 , wherein the non-uniform underlayer refractive index of the underlayer changes from being relatively similar to the waveguide refractive index to being increasing different from the waveguide refractive index as distance is increased from a light injection location.
