Abstract

A device including a waveguide having a first waveguide surface and a second waveguide surface parallel to the first waveguide surface is disclosed. The device may include a first light coupling device operatively coupled to the waveguide. The first light coupling device may include a first duct structure and a second duct structure oriented to reflect in-coupled light. Each of the first duct structure and the second duct structure may includes a first planar region and a second planar region parallel to the first planar region and a first surface and a second surface parallel to the first surface. The device may also include a second light coupling device disposed between the first waveguide surface and the second waveguide surface. The second light coupling device may be to positioned to receive reflected in- coupled light from the first light coupling device.
