Abstract:
Systems, devices, and methods that implement waveguides in curved transparent combiners that are well-suited for use in wearable heads-up displays (WHUDs) are described. Curved transparent combiners employ an optical lens or optical lens blank with a waveguide or light guide embedded therein and with low refractive index materials interposed between one or more major surfaces of the waveguide and the optical lens or blank to facilitate total internal reflection while the waveguide is embedded in the lens. The curved transparent combiners may optionally include in-couplers and/or out-couplers to provide transparent combiners that substantially match a shape, size, and geometry of conventional eyeglass lenses and can, in some implementations, embody prescription curvatures to serve as prescription eyeglass lenses. The waveguides and in-/out-couplers are planar or curved depending on the implementation. WHUDs that employ such curved transparent combiners are also described.

Claim (Index 5):
The transparent combiner of  claim 1  wherein a ratio of a refractive index of the waveguide and a refractive index of the first layer of the low refractive index material is greater than or equal to 1.8.
