1. A method of constructing an electronic circuit assembly comprising the steps of:

  • a) forming at least one electrode on a substrate;

    b) forming a layer of undercladding material upon the substrate and over the electrode;

    c) forming a wave guide core layer on said layer of cladding material;

    d) patterning said wave guide layer to produce at least one optical wave guide and exposed undercladding material;

    e) forming a layer of overcladding material upon the exposed undercladding material and over the optical wave guide;

    f) forming at least one via aperture through said overcladding material and said undercladding material; and

    g) disposing a conductive material in said via aperture to produce an electronic circuit assembly.
