Claim:
1. A digital system comprising a dielectric core waveguide, wherein the waveguide comprises: a longitudinal dielectric core member, wherein the core member comprises a body portion and a transition region; a cladding surrounding the dielectric core member; wherein the body portion of the core member has a first impedance; and wherein the transition region of the core member has a graduated impedance value that gradually changes from the first impedance adjacent the body portion to a second impedance; further comprising a substrate having a surface, wherein the waveguide is formed on the surface of the substrate, wherein the waveguide comprises: a conformal base layer formed on the surface of the substrate; and two spaced apart sidewalls and a conformal top layer connected to the base layer to form a longitudinal core region.
