Abstract
An optical panel is disclosed. A plurality of stacked planar optical waveguides are used to guide light from an inlet face to an outlet face of an optical panel. Each of the optical waveguides comprises a planar sheet of core material having a central plane. The core material has an index of refraction which decreases as the distance from the central plane increases. The decrease in the index of refraction occurs gradually and continuously.

A plurality of stacked planar optical waveguides for an optical panel, each optical waveguide comprising:
- a planar sheet of core material having a central plane, the core material having an index of refraction which decreases as the distance from the central plane increases.
An optical panel, comprising:
- a plurality of stacked optical waveguides, each optical waveguide having a first end and a second end, wherein an outlet face is defined by the plurality of first ends, and wherein an inlet face is defined by the plurality of second ends, each optical waveguide comprising a planar sheet of core material having a central plane, the core material having an index of refraction which decreases as the distance from the central plane increases.
