Claim 15:
16. The method of claim 15, wherein the of forming the first trenches and the step of forming the second trenches each comprises:
forming a photoresist with a trench pattern on the substrate;
exposing at least one portion of the photosensitive glass substrate to an activating energy source;
heating the photosensitive glass substrate a first time for at least ten minutes above a glass transition temperature thereof;
cooling the photosensitive glass substrate a first time to transform at least part of the exposed glass substrate to a crystalline material to form a glass-crystalline substrate;
etching the first or second trenches in the glass crystalline substrate with an etchant;
flood exposing a region outside of the etched first or second trenches of the photosensitive glass substrate to the activating energy source;
heating the photosensitive glass substrate a second time for at least ten minutes above the glass transition temperature thereof;
cooling the photosensitive glass substrate a second time to transform the exposed glass substrate to a crystalline material to form a glass-crystalline substrate; and
selectively filling the trenches with a conductive material ground plane and input and output channels with one or more metals, wherein the one or more metals are connected to a circuitry.
