Briefly, in accordance with one more embodiments, a substrate guided relay for a photonics module includes a slab guide having a first end and a second end, and a first surface and a second surface. An input coupler disposed at the first end of the slab guide at an interface between the input coupler and the slab guide receives an input beam and feeds the input beam into the slab guide which generates multiple copies of the input beam. An output coupler disposed on the first surface of the slab guide causes the multiple copies of the input beam to exit the slab guide via the output coupler as an output. A homogenizer disposed on the second surface of the slab guide reflects at least some of the multiple copies of the input beam to increase uniformity of the output.
