Optical waveguide structures
 An optical waveguide structure for distributing light from a light source includes a cylindrical sleeve configured to accommodate and receive light from the light source. The sleeve includes a central axis. A waveguide collar is formed from a solid, planar block of material. The block of material has a central portion configured to accommodate and surround the sleeve. The first and second output arms extend in a plane away from the central portion. The plane is substantially perpendicular to the central axis.
