Luminaire utilizing waveguide

An optical waveguide comprising orthogonal x- and y-dimensions and developing an illumination distribution pattern comprising orthogonal x- and y-extents, comprising:

• at least one coupling cavity for directing light into the waveguide;
• at least one light redirection feature disposed within the optical waveguide for redirecting light in an x-y plane within the waveguide;
• and
• at least one light extraction feature for extracting light out of the waveguide in an illumination pattern;
• wherein the illumination pattern comprises at least one of the x- and y-extents that is offset with respect to the x- and y-dimensions, respectively;
• wherein the at least one light redirection feature, the at least one light extraction feature, and the least one coupling cavity are disposed on first, second, and third sides of the optical waveguide;
• and
• wherein the third side is transverse to and between the first and second sides.
