Abstract
A method of constructing an electronic circuit assembly comprising forming at least one electrode on a substrate; forming a layer of undercladding material upon the substrate and over the electrode; and forming a wave guide core layer on the layer of cladding material. The wave guide layer is patterned to produce at least one optical wave guide and exposed undercladding material. The method of constructing further includes forming a layer of overcladding material upon the exposed undercladding material and over the optical wave guide; forming at least one via aperture through the overcladding material and the undercladding material; and disposing a conductive material in the via aperture to produce an electronic circuit assembly.
