Abstract:
An eyepiece waveguide for an augmented reality. The eyepiece waveguide can include a transparent substrate with an input coupler region, first and second orthogonal pupil expander (OPE) regions, and an exit pupil expander (EPE) region. The input coupler region can be positioned between the first and second OPE regions and can divide and re-direct an input light beam that is externally incident on the input coupler region into first and second guided light beams that propagate inside the substrate, with the first guided beam being directed toward the first OPE region and the second guided beam being directed toward the second OPE region. The first and second OPE regions can respectively divide the first and second guided beams into a plurality of replicated, spaced-apart beams. The EPE region can re-direct the replicated beams from both the first and second OPE regions such that they exit the substrate.
