Abstract
Windows, or other types of transparent materials, may be constructed to passively allow light from alternate sources to pass therethrough, while also being able to actively produce artificial light for providing illumination from one side of the window by means of an incorporated optical waveguide that accepts light from an edge of the window and disperses it from only one side of the window.
