Abstract
Three dimensional electronic and optical coupling devices that are capable of providing high speed coupling over a large frequency range while limiting the amount of space consumption in the communications network. An optical or electrical coupling device comprises a first substrate and a second substrate adjacent to the first substrate having one or more optical waveguides or microstrips formed thereon. The substrates will have disposed thereon conductive microstrips and/or dielectric elements. The one or more optical waveguides or microstrips formed on the first substrate correspond to at least one optical waveguides or microstrips formed on the second substrate so as to facilitate optical coupling between the corresponding waveguides. Precise spacing between the substrates and precise spacing between the optical waveguides or microstrips facilitate the requisite optical/RF coupling.
