ABSTRACT:
An optical device for collecting light and selectively outputting or concentrating the light. A layer has an optical index of refraction n.sub.1, and top, bottom and side surfaces intersecting to define an angle of inclination .phi.. A back surface spans the top, bottom and side surface. A first layer is coupled to the bottom surface of the layer and has an index of refraction n.sub.2. The first layer index n.sub.2 causes light input through the back surface of the layer to be preferentially output into the first layer. A second layer is coupled to the bottom of the first layer and selectively causes output of light into ambient. The layer can also have a variable index of refraction n (x, y, z).
