1. A luminaire, comprising:
- a first waveguide and a second waveguide, each of the first and second waveguides having a first end and a second end, wherein the first waveguide comprises a first coupling surface extending between a first surface and a second surface opposite the first surface, wherein the second waveguide comprises a second coupling surface extending between a third surface and a fourth surface opposite the third surface, and wherein the first and second coupling surfaces define a coupling cavity extending along a length dimension of the first and the second waveguides between the first end and the second end and the coupling cavity separating the first waveguide and the second waveguide;
at least one light source within the coupling cavity; and
a light diverter disposed in the coupling cavity, wherein the light diverter extends along the length dimension of the first and second waveguides.

Abstract
A luminaire includes at least first and second waveguides. The first waveguide has a first coupling surface extending between a first surface and a second surface opposite the first surface, and the second waveguide has a second coupling surface extending between a third surface and a fourth surface opposite the third surface. The first and second coupling surfaces define a coupling cavity. The luminaire further includes at least one light source within the coupling cavity.
