Abstract: Light guide assemblies including first, second and third light guides, a first optical coupling component disposed between and attached to the first and second light guides, and a second optical coupling component disposed between and attached to the second and third light guides are described. The first optical coupling component is adapted to couple light between the first and second light guides, and the second optical coupling component is adapted to couple light the between second and third light guides. The first light guide, the second light guide and the first optical coupling component are coextensive over a first region of the assembly, and the second light guide, the third light guide and the second optical coupling component are coextensive over a different second region of the assembly.
