Abstract

A waveguide is disclosed. The waveguide (40) includes a light barrier (42) with a surface between sides. A light signal carrying region is positioned adjacent to the surface (58) of the light barrier. A drain (59) is positioned adjacent to at least one side of the light barrier. The drain is configured to drain light that exits the light signals carrying region from the waveguide.
