Abstract
The present invention provides a planar waveguide. In one embodiment, the planar waveguide includes first and third layers formed above a substrate and adjacent each other. The first and third layers are formed of a first material having a first index of refraction. The planar waveguide also includes a second layer formed between the first and third layers of a second material having a second index of refraction that is larger than the first index of refraction. The planar waveguide further includes a plurality of organo-functional siloxane based resin or polymer waveguides formed in the second layer. Each organo-functional siloxane based resin or polymer waveguide has an input on one edge of the second layer and an output on one edge of the second layer so that the input and output are on different line-of-sight paths. The plurality of organo-functional siloxane based resin or polymer waveguides is formed such that intersections of the plurality of organo-functional siloxane based resin or polymer waveguides occur at approximately right angles.
