Two-layer electrical substrate for optical devices |
摘要 |
A high performance and small-scale circuitry substrate is described. The circuitry substrate includes a dielectric layer, a return plane attached to a bottom surface of the dielectric layer, and a plurality of return paths (ground) and signal lines that are attached to a top surface of the dielectric layer. The return paths on the top surface are connected to the return plane on the bottom surface by wrapping around at least one edge of the dielectric material. Return paths on the top layer can also separate each pair or adjacent signal lines. The circuitry substrate can be advantageously used to form an optoelectronic module.
