Abstract: Systems, devices, and methods for expanding the eyebox of a wearable heads-up display are described. A light guide with an expanded eyebox includes a light guide material, an in-coupler, an outcoupler, and a gradient refractive index (GRIN) material. The in-coupler and the out-coupler may comprise a GRIN material. An eyeglass lens with expanded eyebox includes a light guide with expanded eyebox. A wearable heads-up display includes an eyeglass lens including a light guide with an expanded eyebox.

Abstract: A waveguide including at least a first photopolymer layer and a second photopolymer layer having a barrier layer therebetween and a first transparent layer and second transparent layer overlaying the first and second photopolymer layers, respectively. The waveguide can further include at least one holographic incoupler and at least one holographic outcoupler, each configured to be responsive to light within a first waveband and unresponsive to light outside of the first waveband, and further configured to be transmissive or reflective.

Abstract: There are provided holographic optical elements (HOEs) and methods of making the same. An example of such methods includes recording a first hologram in a contiguous holographic recording medium of the HOE. The first hologram may receive a beam of light and direct at least a portion of the beam into a light guide to form an incoupled beam. The method also includes recording a second hologram in the contiguous holographic recording medium. The second hologram may receive at least a portion of the incoupled beam and direct the portion of the incoupled beam out of the light guide to form an outcoupled beam. In addition, the method includes affixing the holographic recording medium to the light guide.
