1. A system comprising:
a waveguide having first and second substrates, the first substrate having a first planar surface and a second planar surface parallel to the first planar surface, the second substrate having a third planar surface and a fourth planar surface parallel to the third planar surface, and the third planar surface being parallel to the second planar surface;
a spatial light modulator (SLM) having a lateral surface parallel to the fourth planar surface;
a holographic grating medium interposed between and in contact with the second and third planar surfaces, wherein the second substrate is interposed between the holographic grating medium and the SLM; and
a grating structure in the holographic grating medium and configured to diffract incident light toward the SLM about an axis forming an angle with a surface normal of an active area of the SLM.
