Claim:
1. An optical waveguide body comprising orthogonal x- and y-dimensions, comprising: at least one coupling feature for directing light into the waveguide body and the at least one coupling feature extending into the waveguide body from an end surface; at least one light redirection feature extending in the x- and y-dimensions for redirecting light within the waveguide body; at least one first light extraction feature extending in the x-dimension for extracting light out of the waveguide body; at least one second light extraction feature extending in the y-dimension for extracting light out of the waveguide body; and at least one light extraction rib extending in the y-dimension and disposed within a first side of the waveguide body transverse to the end surface; wherein the at least one first light extraction feature, the at least one second light extraction feature, and the at least one light redirection feature are disposed within a second side of the waveguide body transverse to the end surface; wherein the at least one first light extraction feature and the at least one second light extraction feature comprise first and second sloped surfaces, respectively, and the first and second sloped surfaces face different directions.
