Original Abstract Submitted

A waveguide including first and second sections has a first molded optic material forming a portion of the geometry of one or more Bragg gratings disposed on one surface of the first section of the waveguide. Similarly, a second molded optic material forming another portion of the geometry of one or more Bragg gratings is disposed on one surface of the second section of the waveguide. Further, a photopolymer material is deposited on the first molded optic material. As the first and second sections are coupled, a waveguide is formed with a layer of photopolymer material disposed in the waveguide with the layer of photopolymer material having a geometry defined by the first and second molded optic materials. Bragg grating holograms are then recorded in the layer of photopolymer material, resulting in a waveguide with a plurality of Bragg gratings.
