Dielectric waveguide having a core and cladding formed in a flexible multi-layer substrate

A system comprising:

• a multilayer substrate having at least a core layer having a first dielectric constant value, a top layer adjacent the core layer and a bottom layer opposite adjacent the core layer, wherein the top layer and the bottom layer have a dielectric constant value that is lower than the first dielectric constant value;
• a dielectric waveguide (DWG) formed within the multilayer substrate, wherein the dielectric waveguide comprises:
• a longitudinal dielectric core member formed in the core layer having two adjacent longitudinal sides each separated from the core layer by a corresponding slot portion formed in the core layer, such that the dielectric core member has the first dielectric constant value;
• and
• a cladding surrounding the dielectric core member formed by the top layer and the bottom layer infilling the corresponding slot portions of the core layer, wherein the cladding has a dielectric constant value that is lower than the first dielectric constant value.
